I've got a Note 10.1 2014 mounted in the dash of my truck to replace the radio and am on a mission to figure out how to get USB OTG to work with charging. I've read an ocean of threads regarding hacking MHL adapters, but there is not any information specific to the Note 10.1 2014.
Right now I've got a relay system in the dash that switches between a OTG cable and a charge cable depending if the ignition is on or off. This works for my basic purposes, but if I use GPS navigation and wifi tethering, I run the battery pretty low after only 3-4 hours. When I turn off the truck it begins charging, but that wont work for a road trip.
I've tried the Samsung smart dock (without reading that it wouldn't work), and of course, it doesn't work, although it would be the perfect solution.
My idea is that there would be some way to use the 11 pin MHL connector on the device to get what I'm after. Looking at the pinout, it seems that there are some USB host pins within the 6 additional MHL pins, but I do not know of anyone who has tapped into them and had OTG working.
Is anyone else trying to get this to work on a Note 10.1 2014? I'm happy to hack up and solder anything and everything imaginable to give it a try, but I'd like to collaborate about it and see if we as a group can get this working.
Im about ready to rip apart my smartdock and see exactly why it wont work with this tablet.... have no idea why it qont recognise the tablet...

Man, you really gotta get us a screenie of this! That's bad ass.

Meanwhile, is there a possibility for that knock-out?
High current charging has an impact on the signal lines. So USB 2.0 current is limited to 500mA, or probably the 900mA from USB3, if the port can provide it. On a standard USB2 port the Note remains self-powered. And even with 900mA it will slowly discharge while in use, despite the battery charging at max current. On a 2A charger, the operating power bypasses the battery, which is much more healthy for it.
Thank you for your reply. Unfortunately I asked imprecise. What I liked to ask is, if there is meanwhile a possibility to charge the tablet while using the usb connection e.g. with an external hard disk?
Almost certainly not. Samsung could have provided a charger jack, or even support wireless charging. But it was not meant to be.
I just tried one of the charge and 2 female usb adapters off ebay and it didnt charge. It detected the usb connectors connection, but wouldnt charge.
$5 lost...
Did you used the wall plug? Because the tab needs 2A for charging...

Why not take away the USB requirement? I assume you want this to allow external storage, in this case get some sort of NAS that can be 12V powered and install that in your truck then allow the Note to connect to this via Wifi, then the USB port can be dedicated entirely for charging only.
Plus you have the benefit that when at home you can transfer file to your NAS without needing to leave you PC.

Are you using the LTE/3G for internet access? if not then setting up a wireless network in your truck might work. I use a HooToo TM001 (also have the TM002) to do this set up. The hub has a 6000mah battery that when the USB drive is not installed can charge a device.
i know it's been a while since OP posted, but i've been using a wireless HD so i can use external storage and maintain a charge. if you get the seagate wireless plus, you'll be able to charge and stream at the same time as long as you use a usb3.0 cable to charge from (it's included). using a 2.0 cable will turn off wifi.
it's quite a bit more than OTG, but it does allow you to have tons of storage available while still having a charging option.
I use a nexus 7 in the dash of my car (sure do wish I had space for the note 10.1 in there though!) With the nexus 7 I bought a y-cable that allows me to charge AND use otg functions. However, a specific kernel was needed im pretty sure. I set it all up a while back so I cant remember specifically sorry. Its all nexus 7 forums here though.

yeah mate, i'll have a look for you. the nexus 7 is out of the car now cus im trying to make a custom facia to fit the samsung note 10.1 in there. so I'll have to charge it up and have a look which kernel it was running. but im pretty sure it was just the default one that came with the AutoDroid rom in the nexus 7 forums.
if you don't hear back from me just pm me, I'm forgetful as hell and its coming into exam time....so yeah

While researching ability to use USB DAC while charging the phone in the car I found this video. The guy clearly says that tablet is charging while accessing all those accessories via USB OTG. Similar cables are found on ebay, called "USB OTG with power".
The big question is: would the Galaxy S3 actually charge while using USB DAC at the same time? It should be possible, but I don't have the phone yet (still considering it), nor do I have the cable, nor a USB DAC In theory it should be the same with any accessory - can someone actually confirm either way, whether phone can or can't charge in USB OTG mode with similar cable? This video shows similar setup on Galaxy S (only it's normal OTG cable, USB hub, usb Y-cable and card reader) and it's definitely charging while mounting USB devices! Will S3 do the same?
I fear that upgrading from Galaxy S with voodoo control of Wolfson chip to north-American S3 with worse audio path might not suit me if there's no way to power the phone and use external DAC at the same time in the car... I hope there is a way... I appreciate any advice and opinions.
It's a first time I see such cable...All I read was people saying it's impossible in the first place. Well, hopefully in 2 weeks I'll be able answer your question

Looks like it's possible on some devices, but not with Galaxy and Nexus family... But it would be great if you can confirm that, so let me know if you can try it. Thanks.
Finally got the cable.
The result - nope, doesn't charge
Maybe the "Allshare hub" could do what your asking for?

Sonic, any luck with your friends phone? Really looking foward to your results :fingers-crossed:
Do you have part #s for the variable resistors in your samsung post or at least where you got them from? I would be willing to try some things out if I could find the right pieces. What I really want to get my hands on is the MHL adapter that was shown off with that spider laptop at IFA a couple weeks ago..
SUCCESS!!! I can confirm that this USB OTG cable (http://ebayitem.com/190710044655) DOES CHARGE MY GALAXY S3! I plugged in USB cardreader with SD card into the phone through this cable (it lit up and card is fully readable), then plugged USB cable end into PC and phone showed a charging icon! Moreover, after waiting for 5 min. with screen off (cardreader still glowing blue and working) battery has gone up from %72 to %75 (and while I was writing this, to 78%), so it is indeed charging! Yay! It probably won't get up in the car, where just phone alone is "not discharging" at best from the car adapter, but at least it should allow me to listen to music with quality DAC and use navigation without (or with minimal) discharging.
I have not tested it with USB DAC that I intend to use for my car (Behringer UCA222), because I have to go out and buy it. Hopefully it works. Anyway, this cable definitely works with simultaneously charging my north-american Samsung Galaxy S3 (from Bell Canada) while powering USB cardreader!
Somebody else has mentioned that another cable (http://ebayitem.com/120980364117) also worked in his Galaxy S2.
I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power that I mentioned. It works great! And the phone is indicating a charge. Sometimes when first playing music after plugging the device it sounds like fast forward for a few seconds (I guess clock rate mismatch or something similar), but after the presumably clock is locked it plays perfectly fine.

That is outstanding..gonna order one of these guys right now.
Here is a better link for all the ebay listings. Be aware of the differences, MicroUSB adapters would allow you to use your existing charge cable to plug into it while the standard USB would require you to be very close to the charger or have a USB A-A cable to attach to a power source.

The problem is that apparently not all of those cable work in terms of charging the phone. People say mostly that it doesn't work. The only guy mentioned success is with the cable I bought, but he then confirmed it with another, more convenient cable. I have the one that needs a USB extension cable to reach the charger, but it's about a buck on ebay, so no problem there. But not all cables work this way: most reportedly will allow you to power USB accessories but not charge the phone.
I found that this configuration works for charging while in USB HOST mode:
S3 -> standard otg cable -> Powered USB2.0 HUB -> devices (keyboard, usb dac, usb hdd...)
The only catch is that the hub must be powered before you plug in the phone or the phone will try to power the hub and will never enter charging mode. I'm using this setup in my car and it works perfectly. As long as I start the car before plugging the phone, we are good to go.
I only confirmed this works with AOKP JB builds. No idea about other roms/kernels. Hopefully this helps someone.

I got mine in the mail today (ordered 10/16) and tried it out as soon as I could. I can confirm it charges and allows for OTG at the same time. This is the auction I bought from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=251127542280&ssPageName=ADME:L:eek:U:US:3160
Hello y'all. I'd like to ask your attention to this thread, especially but not limited to sonicboom and others, I really could use some help.
***EDIT***
USB Host DOES work with Flash Drives. For information see post 3: http://forum.xda-developers.com/showthread.php?p=37201971#post37201971
This is now my main focus. So I figure why not everyone post up what devices they got to work with the Kindle Fire 2 and/or what methods it took for you to do so.
3x Different Flash Drives: Not Working However one of their LED's Illuminate
USB Keyboard: Not Working
Logitech M570 Wireless Trackball: Working
I also tried a non powered hub, it didn't work. The Green LED Illuminated but nothing more. When connected to my Galaxy S 3 I can have multiple devices attached at a time. I tore the Hub down and found that it has a blank slot for power. I wired soldered in a 0.75a Samsung Wired Charger to it. It Illuminated the LED, As well as it illuminated the Power LED in Orange on the Kindle but no devices worked on the Hub. I tested the power output of the USB Ports and it was a little more than 5v per port.
Device: Kindle Fire 2
Rooted and TWRP'ed with the Nightly of CM10.1 1-20-2013
Will keep trying. As stated in another thread, that its simply power. After testing these things out, I don't think its power related. Either the kindle just doesn't have the "Drivers" if thats what you'd call it, or it simply can not run anything but a mouse. I hope that is not the case. It will ruin all appeal in my eyes.
If you're rooted, have you tried installing StickMount?
Might work for the flash drives.
I tried, Stickmount tries. You can tell its trying to work something out. So more tests with a cut up usb cable on the OTG cable does in fact show there is a voltage issue. My Galaxy puts out perfect 5v. The Kindle puts out around 2.5v. I tried making another OTG cable but failed. I guess its just not getting connection to the extra pin. So I have a USB Extension I'm gonna split open and power it. So I don't have to hack up my only working OTG.
The main issue I'm having with this is, my current power unit is a measly 0.75a. And It charges the device. So I figure there will still be a voltage issue due to the device charging. So I could cut the red wire going to the device for now. But not sure if the device will realize this somehow and just not work. Thoughts? I've seen this done before when someone made themselves a powered OTG Hub system out of a couple USB Cables.
I'll continue till I'm too tired to think hehe.
***Edit***
Ok couple hours later.... lol I had a USB Extension, I cleanly just slit it down the m iddle and soldered in the two power wires from a samsung micro usb charger. The Power is 5v at 0.75a. So its not much. I know it wouldn't charge my nexus nor Galaxy Tab, but it charges the Kindle, or at least the kindle says it is. I doubt it really is. Anyway I soldered it in, cleaned up the surgery started some testing on my phone first. I connected a Micro USB cable to one end and then the other to my phone, and then the Kindle. It charges, or again says it is (*kindle might require more amperage). So Next I connect the OTG Cable to the other end and connect it to my phone, It charges through the OTG Cable. Next the Kindle, it does not charge the kindle. Possible amperage requirements, I don't know yet.
So onto the test without StickMount, Failure. It acts the same.
Test with StickMount, Well I'll let this screen shot explain most of it:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It worked! StickMount notification pops up and I found the flash drive in the current location. Inside the SD Card under a folder called /usbstorage/sda1/. Not exactly my first choice, not sure if this can be changed to go into mnt or somewhere else. The Device itself doesn't notice the flash drive. So if you go into System/Storage, it does not show the flash drive. But it is fully functional. I accessed some files without any issues.
So my final consensus: The Kindle Fire 2 currently has OTG/USB Host Capabilities. From the USB Host Diagnostics I ran, its fully functional. However the main issue is Power. The second issue is the device on the most current (1/20/2013 CM10.1 Nightly) rom doesn't have the proper... I don't know the right wording for it, but lets say drivers since I'm a pc guy. I'm sure with more development, it can control any device with the only issue being power related. This takes away from the meaning of "On The Go". Having some sort of 5v power source connected to your device while your trying to use a hard drive or something else is going to be a pain in the ass for most people. For me it really does not matter since the device is going to be setup in my car for media sourcing as well as game play. So a 32gb flash drive and a Xbox 360 controller is all I will be using.
I will be doing more testing with multiple devices but it is 4am right now. One more thing, Bluetooth abilities are possible with a cheap dongle. However for some reason the Kindle recognizes it as a physical keyboard. I have tested this on other devices in the past so I believe it is possible with some more development. But that's far in the future and still of course require additional power.
Goodnight guys.
I have 3 different thumb drives.
Sony 4GB = does not work
SanDisk cruzer slide 16GB = does not work
SanDisk cruzer 8GB = Works
The regular cruzer is probably 5+ years old. I have access to others and will update my post when I get them.
I'm on PowerPoint45 cm 10.1 using chainfires stickmount.

Nice. The regular flash prob requires less power. I noticed one of mine which was larger almost worked. But would shut off prob to not enough power. But a newer one wouldn't light up at all.
Plans for today: To re build that USB Hub I was messing with last night. I desoldered the USB cable off of it to solder in a Micro USB, But I don't remember if it worked. I then tried to turn it into an OTG direct 4port hub but nothing happened. So I'm sure I screwed something up. But the initial results should be a powered, 4port Micro USB OTG Hub. I just hope I have enough juice to make it work for not only charging the Kindle but powering the devices on the hub. I have a Galaxy Tab Official 2.0a car charger I can try out. I want to be able to have at the least, a 32gb Flash Drive and a 360 Gaming Controller.
Well I got some done today. I found an old phone charger that was 1a. I finally just used my OTG Cable and soldered it in place of the std usb connector on a cheap USB Hub. I'm sure everyone has the same hub I'm using, I have two, one says Microsoft on it, the other says AMD but they are super cheap and are given out everywhere you go:
Its a non powered USB hub, however when opened up there is a bare spot for a power connector. Middle pin is 5v + and the two around it are common Ground -.
Don't be strayed by my crap solder work. I'm using a cheap harbor freight soldering iron and the new charger has very thick wire so it didn't really fit in the small holes. The ground is just directly connected to everything else thats ground related so I grounded it there. That way the two wires aren't soo close together.
I have now successfully tested 3 flash drives, NTFS, Fat32 and some strange Fat32 drive plus my Trackball. As well as this I have successfully charged my Galaxy SIII off of the hub. I wouldn't exactly recommend this unless your running like a legit 2a charger. I only did it to test out power requirements. I think either my cable is damaged too or I'm at the limit of power the small 1a can handle because every once in a while the hub shuts off. I think its just cable related.
Here is everything connected as you can see.
However the tablet it self is not charging. At least the icon on the notification bar doesn't say so. I have tested the voltage here and its 5v. But IDK? Maybe the Kindle wont allow it? BUT, with all my testing, the battery has stayed at 88%. I'm gonna try to kill it some more. Maybe with some transferring files between drives.
lol As I'm typing this, I sit down for a second with the tablet on the carpet floor and just stare at it. I've noticed that some reason the led turns off and on at random times. But I've never seen it say its charging. Well the screen just dimmed but didn't shut off so I get up to check real fast and when I turn it on, it says 88% - Charging! But then instantly goes back to 88% - Not Charging when the screen lights up. And there it goes again (Please bare with me as I'm doing this all this very second.) Looks like it just needs some more amperage. 1a is not enough to power everything and charge the device.
I was worried that the kindle wasn't going to support Charging OTG. Well I happen to have a spare 2a Galaxy Tablet charger and no Galaxy Tab.... I'll try it out and get back to you guys!

This looks good! If you want, once you are done with the testing, I can try and write up a guide with your words on how to do it then let you post that. I did the same for some of the stickied threads. It looks like you're almost done and I think this would be a really good info thread once compiled nicely. Stuff like how to do OTG, what works, what needs a powered HUB, stuff like that. I personally will probably never use OTG, but I see the value and I like what it can be used for.
Best of luck!
That's nice. lol I understand I talk a lot, but when it comes to things I must have, like more than 5gb of memory on a device that should have a few TB . It would be nice for others to try out things to see what works and what doesn't. Because to have a powered USB Device is kinda not the point of OTG "On The Go". But like someone figured out that one of his older Flash drives worked, so hopefully others chime in too.
If you wanna do that, you have my approval. Just make sure it suits what I did, "Dedicated OTG". or "Guaranteed OTG". Since that's what I was mainly working towards. This discussion thread is mainly to locate what works and what doesn't and the main OTG Capabilities of the Kindle Fire2. I don't plan on changing much else to what I have already done except adding a larger psu to the hub so it charges the device while powering the hub and its devices for my own personal gain. I want to keep this open so people can throw up what they have learned as well so the information is out there for others. I personally hate going into a device and not knowing.

I should get an OTG cable. I have a small flashdrive, not sure about the name or brand since the size made it temporarily misplaced. It's the same size as the wireless receivers though for most modern mice and keyboard so it's SUPER small, which I actually wouldn't mind tucking the cable into my case, plus it's 32GB. The issue on PC, is the transfer rate is a little low, but that may be because it uses so little power, which I'm hoping.
Any good places to get an OTG cable?
Ebay, Amazon (great place for cables)
https://www.google.com/search?q=OTG...29,d.aWc&fp=4a19662fa4882be9&biw=1920&bih=965
Just a quick search. You can also make one, if space is an issue. You just need a MicroUSB and a female USB. Pin 5 gets soldered to pin 4 on the MicroUSB and bam! Making one would help with space issues since you can tuck the wires easier. If you are good at soldering.

Just a quick search. You can also make one, if space is an issue. You just need a MicroUSB and a female USB. Pin 5 gets soldered to pin 4 on the MicroUSB and bam! Making one would help with space issues since you can tuck the wires easier. If you are good at soldering.

Is an OTG cable special or just F-USB and M-MicoUSB?
If it's just those, then I can go poke around Frys and Radioshack for one.
I don't know anything about soldering, how much is a good kit to get started? I think a friend of mine has one and knows how to use it, so I can ask him, but I realize it's something I should learn especially with the hardware mods I would love to do. If I can't find a cable in stores, or if it's special (I ask that because most employees at frys and whatnot aren't very helpful or knowledgable, so I don't want them giving me something that won't work, but if it's just those ends I'm looking for, I can do that) then I may just look into soldering my own and learning that. I see they're around $50 online but I don't want to screw myself over there.
You can chose a decent soldering iron anywhere from 15 to like 80 bucks. I recently saw some nice ones with adjustable power levels for good price. And tons of different tips. My brother Skorpn has the more expensive one that heats up fast and has adjustable power settings to fit any projects needs. Hr has a nice soldering station I wish I could use more. I however just have a cheap harbor freight iron with a fine tip from radio shack and I use the thinnest silver solder avail there as well. Flux is also a must.
Anyway. Otg mode is accomplished on the micro USB side. They have 5 pins instead of 4. The 5th is used for doing all sorts of things with the right add one tho. If you solder in a small wire to it and jump it to pin 4 which is ground, it turns on otg. Not really hard to do. You can make one decently. Just need a good micro USB cable and a female normal USB cable. Solder them together and then do the otg modifications.
Other than doing it yourself, they are very cheap. But if you have the spare cables, it doesn't hurt to play around.

I've got my USB mouse to work using otg cable, is there any chance using it could damage my kindle, this Mount app I use says it can damage the kindle because of the power output
Sent from my Amazon Kindle Fire2
I don't know what ap your talking about. But no. The Kindle Fire 2 only puts out half the voltage when in OTG Mode. So only certain things will work without additional power. Your mouse will work just fine, especially if its a wireless mouse, since the wireless device doesn't require hardly any power. Some other devices will work too. You don't need a mount app for using devices, only for Flash Drives. And so far out of every one I've used the best one is Chainfire's StickMount. Chainfire is the creator of Superuser.
Anyways, I'm not using a 2a charger to power my USB OTG Hub, and it powers all 4 devices and charges the device with ease. Cannot wait to have this thing installed.
OTG testing
After reading this thread I thought I would have a go and do some testing myself. so I found a USB y cable teamed that with a female to female USB adaptor so it would extend my OTG cable but allow me to pipe in some power (5v off a arduino) off the y cable. I have got my mouse working and USB flash drive but I cant get my Xbox 360 wired controller to work

You know the amperage of the power source you are using? It might just be not enough power. Because the device itself will take from it also. Its pretty much splitting it. Which is why I went with a legit Galaxy Tab 2a charger since its one of the most powerful chargers I've come across. I hope it works. Since bluetooth doesn't work on the OTG yet, I need the 360 controller to work. I will be trying a wireless controller and one of those Microsoft adapters soon. Hopefully it works! I'd love to play some video games in the car

You have a good point there, I haven't tested the amperage that comes out of a arduino but I don't think it would be much. I could try and hock up a iPad charger which I think is 2amp.

I have just tested the Xbox 360 controller being powered from a iPad charging plug and now joy. It lights up but then goes off
I'm making my own otg cable tonight if the spare usb cable I found works for data and not just charging. Basically I have a female usb port on a cable that I used to splice in with an original Xbox controller plug to be able to use usb sticks as memory cards for my Xbox to be able to install gentoo Linux on my Xbox (original Xbox controllers are usb 1.0 with a proprietary plug type) so I know the female port works fine for data transfers.
Eventually I'll buy some plugs to solder onto both the usb and Xbox cables so I can yank the female plug from the otg cable and snap it right onto the Xbox plug instead of having to constantly re-splice them or buy a new usb extension cable for the female end/buy a pre made otg cable.

IDK how thats going. I don't think anyone is working on it since the KF2 doesn't have bluetooth to begin with. When I connect my cheapo BT Dongle, it doesn't allow me to turn the switch to on. However it does see the BT Dongle and thinks its a keyboard of some sort. Which would be nice because I have a really nice BT Keyboard for Android I wanna use.
Also would be nice to use PS3 Controllers. I'm going to attempt the wireless 360 controller with the adapter one of these days, whenever I can focus some cash in that direction. I really want a wireless 360 controller on my KF2 so I can play some of the higher end games as well as the older Emulated games. Just think its too cool
I just recently got a Samsung Galaxy Note 10.1 and so far I'm quite happy with it --- except one thing, I cant find a cable that lets me charge the tablet *and* use the USB Host (OTG) port... (i.e. read files off a USB drive or play a game with a USB game pad while keeping the tablet plugged in)
Is there a way to do this? it would seem to me that all it needs is a splice to give power to the Power +/- pins on the connector while keeping the OTG Data +/- pins active...? (I know nothing about the pinout so I could be wrong on this)
Just to be clear I want to use the OTG adapter WHILE CHARGING (I've found one device that gives both these options but says "only one function may be used at a time")
Ideas?
Discussed dozen times in 10.1 forum. Actually it is not possible. Build an otg + power cable myself but it only works with timing and with a specific procedure... quite annoying. Wait for a custom rom somewhere in the future as I do.
You may have issues trying this, OTG cables are iffy under Jelly Bean. Some may work, some may not. In fact, Google removed references to OTG support for Nexus devices last November since OTG is so spotty. Splicing a cable that might work may kill it. Decent battery-powered USB and SD hubs are available and bypass the OTG problems. I have the RavPower RP WD01 and love it. The USB port will support drives upto 3T. It also has an SD card slot.

Powering the USB devices isn't a problem, I have a nice hub that powers them without issue, even extremely power-hungry devices. I was wanting to charge the tablet's battery while using the OTG adapter (original thought was for USB-gamepad-ing since high-requirement games drain battery, but I've since started using a PS3 controller over bluetooth so I can use the OEM charge cable and wireless for gaming --- but USB drives I'd have to copy the files over to internal flash or a MicroSD card to view while charging and i've found that the cards dont like files that are 8gb in size... (FAT-32 restriction iirc))

I saw that when I google'd but thought maybe there had been some new developments (especially with how this site's members love to tinker with electronics and write custom firmware). It's not a huge issue, since the Note 10.1 has amazing battery life (it's actually matching or doing BETTER than my iPad in most circumstances) I just like to never run the battery down low.. (why cant tablets have user-replaceable/swapable batters like most phones?!)
Thanks for the info!
Does anybody know of a working OTG cable for the Nexus 7 2013? If so please reply with a link to Amazon. I am planning to hook up either a ps3 controller or xbox 360 controller.

Using it right at this very moment on my very own N7 2013 built in July 2013
http://www.amazon.com/gp/product/B0073EPXO4/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
This is what I'm using. Cheap & works great & is pretty thick, I feel like it'll last long.
I use this one:
http://www.amazon.com/gp/product/B009YPYORM/ref=oh_details_o05_s00_i01?ie=UTF8&psc=1
purchased from seller: Atomic Market for around $10
It has the additional bonus of being able to accept power via its additional USB cable.
I find the Nexus 7 LTE 2013 does not need the additional power for typical USB thumb drives, but it might be needed for other devices like an external disk drive.
I find my Chromecast must have this cable powered in order to use a USB thumb drive to root and replace the android operating system.
You can save a few bucks for a cable that does not provide power if you want.
I also own this one:
http://www.amazon.com/gp/product/B005FUNYSA/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1
(purchased from amazon seller: Digital Center(Ships From Hong Kong)
which only costs $1.49 with free shipping. It was $0.83 when I purchased it last year.
It works on the Nexus 7 LTE 2013 with USB thumb drives, but does NOT provide additional power for devices which may need it.
Can you confirm thath this otg power cable charges the nexus 7 2013 while still reading peripheral data from usb port?

I can only confirm that both OTG cables I own work on the Nexus 7 2013.
i am using one that came with my minix x5 and it works on all my android devices, but the connection is loose. i would be surprised if there was one that did not work as the cable itself is such a simple thing.
i would also like to know of a working powered option. i thought the powered cables only supply power to the accessory, not to charge the device itself.

Since you have the USB OTG cable with the additional cable for charging, would you mind testing it by:
1). Connecting a working USB device (mouse, HDD, etc.)
2). Connecting the USB power to the 2nd cable in the OTG cable
I am trying to use a BT keyboard and non-BT wireless mouse and charge the N7, but unfortunately, it drains the battery down heavily.
PS: I CANNOT use both BT keyboard and mouse AND have Wifi ON, as it interferes with the BT radio, making the keyboard and mouse lag heavily. I have created a thread on this also.
What thread is that?

I have connected a USB thumb drive. The thumb drive works with or without power attached, but it will not charge. I suppose it is built to provide the power to the attached USB device and not to the phone / tablet.

Perhaps a small powered USB hub will reduce the power drain on the N7?

My y-connector from my n4 doesn't charge while using USB otg. The ability to do so is not written in the software. I'll try to locate the source and report. OTOH, the USB otg connectors from my GNex and N4 all work on my N5 and both old and new N7's.
EDIT: I just ran across this. I'm sure it's for the original N7. I wasn't even aware of it so obviously have not tested it. I did use ziddey's kernel on the N4. Still searching.
2nd EDIT: Available for N7 FLO/DEB 4.4.2. I'm running franco but will revert to stock then try this (as soon as I make a nandroid of my device).
3rd EDIT: That kernel does work to charge while on usb otg. It is a setting you choose to activate during the set-up. I just chose stock everything until I got to the power choices. I will say that although the install was successful, I came as close as I've ever come to thinking my device was bricked. After the install, the screen went black and I couldn't do anything. After about a 30 sec power button mash, everything booted back up. This video shows installation on the N5. Some choices are different on the N7 FHD. As I said above, I was NOT returned to TWRP after installation.
There is a note about altering a sys file for OTG peripherals. I only attached a flash drive and the usb_charge_mode was set to Y (I assume for yes). You may have to perform the edit if using a peripheral device.

Good afternoon,
possibly should already be several topics with this topic, but I can not see if there is the possibility to be able to connect via cable to a gamepad tablet while an external battery .
Does someone can help me ?
Thank you
Game Pads have AFAIK no driver support in Android, except if they can emulate a mouse or keyboard. With a kb emulation or mouse and kb combined, it could well work, theoretically.
But no charging at the same time. Older Notes with their custom port could do such. USB3 offers not much relief, but USB-C could be perfect, with a dock. For the future.
Thanks for your response. so is there any dock that you think works?
Nope, that would have to be an "intelligent" dock with support by the Note's firmware, thus being an official Samsung peripheral. An Usb2 port can draw up to 0,5A during data transfer, but the Note does not charge when active and connected to a usb port, only in standby. Such an "intelligent dock" could charge at 2A while there's no data transfer and also provide MHL and more, but it never got invented...
OK thank you for the information. therefore anything done, even just buying another trablet .
Can you help me.

this cable will works?
The seller tell me that will works.
Thanks
It looks interesting. I don't know how it will handle the charging matter. Probably the current is only run thru the hub while the Note is in standby. But anything else won't work anyway with the Note. I also don't know whether it will deliver 0,5 or 2A and whether you have to remove all attached usb devices first. There must be some logic to switch between data transmission and charge mode and best such is controlled by the Note, but that would have been Samsungs job,to provide something like Microsoft's Continuum. But i'm not sure whether the Continuum adapter can charge the device. This is probably a huge weak point of that concept.
