Micro Usb To Mini USb to Normal USB

I've already ordered the Mine Keyboard and the Adapter to later know that atrix uses a micro USB...
this is the adapter:
http://produto.mercadolivre.com.br/...-conversor-usb-a-fmea-para-mini-usb-macho-_JM
Sure it doesnt fit in atrix. but.. if i buy this?
http://produto.mercadolivre.com.br/...-para-micro-usb-motorola-moto-q11-cpmt018-_JM
and then convert micro to mini then mini to usb normal? would i be able to plug a keyboard? Thanks
or even buy this new one?

you will not be able to plug in a USB peripheral (mouse, keyboard) directly into the phone. it will not work.
you can, however, purchase a +5V powered USB hub (that plugs into the wall), and use that to plug into the phone and plug your KB/mouse into the hub, and it should work. you can find such hubs at www.dealextreme.com
to further answer your question, USB-___USB converters will work as long as the converters have all four lines hooked up. many converters are 'power-only' where only the power/ground lines are connected and the other two lines (data) are not.

So if i buy an ordinary pc hub that connects to power and the plug usb-to-microusb, it will work?

Well let it alone, ill buy a Bluetooth keyboard, will spare time and cables and converters ahahha

The Micro USB plug must be OTG (USB ON THE GO) or your phone won't recognize the peripheral. Also the advice given was correct, the phone USB port can't provide power to a peripheral device and so you must use a powered hub in between the phone and the peripheral device.
A USB OTG has pin 5 and pin 4 tied together in the Micro USB connector end to tell the phone to invoke OTG mode.

Lordareon: yea... if you'd go the wired route, you'd need a powered USB hub, since the Atrix's micro-USB port doesn't work as a host port. It doesn't provide power to external devices.

Has anyone attached two USB devices?

I want to attach two usb devices to my Note.
One will be the MHL adapter and one will be the 2.4ghz wireless unit for a keyboard like this http://www.ebay.co.uk/itm/250996855143.
I need a Micro USB male to 1x Micro USB female and 1x USB female adapter.
These for some strange reason don't exist
I was just wondering if anyone has done anything similar.
I know I could get a Bluetooth keyboard, but I don't have one. I do however have the above keyboard

Oh wow! I'm interested into this keyboard! Does Lenovo Mini Wireless keyboard work perfectly with the Note? All buttons are recognized and trackball mouse is usable?

Its really good, i use it on my Note and my Libretto W100. The mouse and keyboard work perfectly.

You cannot attach 2 or more devices to the same usb port. You need an usb hub for that, but I don't know if the MHL would work with the hub. I will try later today to attach an usb hub and connect more devices, and will report my findings.

Edit:
--------------------------------------------
I have successfully connected a self powered usb hub to the galaxy Note, and connected 2 thumb drives, a combo card reader, and a mouse. The Note mounted both of my thumb drives, as /usbstorage/sda and /usbstorage/sdb respectively. Then I inserted a mikroSD card into the card reader and the phone mounted it as sdc. I then inserted an sony memory stick into the card reader and it was mounted as sdd. All mounts were usable, and I could watch movies from them, and watch pictures, copy files from one to the other, etc... But, when I connected the mouse to the usb hub it didn't recognize it. Whatever combination I tried the Note would not recognize my mouse, when plugged into the usb hub. When plugged directly to the OTG cable it works perfectly, but won't work when connected to the hub (maybe cables are to long).
Using rooted stock xxla6 firmware.
Edit2:
---------------------------------------
Just found out, that usb otg and mhl cannot work simultaneously. When the MHL cable is plugged in, the GNote's microusb port will become an MHL port, and from that point it will not act as an usb host or usb slave. :-(
It's too bad, 'cause I really wanted to connect it to my full hd monitor and use a mouse and keyboard, too.

How about bluetooth mouse+keyboard instead ? That would keep your USB port free for MHL

This is the setup I'm going to do also. But as with topic, it's also very tempting to have everything USB powered. Since it will decrease latency and maybe power consumption as well? (as opposed to bluetooth) Well, MHL to HDMI will still drain our battery even if we connect it to power source
You can also try NZtechfreak's workaround:

MHL with USB OTG?

Has anyone found a MHL cable that also includes a USB OTG port? Samsung reportedly changed from a 5-pin configuration to an 11-pin configuration to allow MHL with USB Host mode simultaneously. Perhaps for a future Desktop Mode?
Has anyone been able to find one of these cables?

Just wanted to update, I believe I found the type of connector that I was looking for, but it is missing HDMI and it is sold out. This essentially could give you PC type connectivity on the S3.
http://www.mobilefun.com/35462-mobile-fun-connection-kit-for-samsung-galaxy-s3.htm

I think we still have a bit of a wait. What you found is essentially a USB OTG hub with some card readers built in. I seriously doubt this will pass through the pins for HDMI to work out of the usb port. We'll see something when this phone finally launches everywhere. It's not even out in the US officially yet

EDIT: Sorry, didn't see the article in the link in the OP. Man.. I might have to get me a GS3 now. I'm quite satisfied with the reasoning for a pin change. =)
Samsung sells 11 pin MHL adapters and USB female to Micro USB male adapters on their accessories page, but I'm not sure if you could piggy back the USB input into the charging port of the MHL cable. I don't see any all in one cables on their site, and the desktop dock is just micro usb/audio. I tried.. =(
Here's what I was looking at.
Old and mostly unrelated. See edit.
I happened to buy what looks exactly like that adapter today earlier at Micro Center. Now, I do have a Galaxy Nexus, but the USB OTG works great with keyboards/usb/mice/hubs; however, I cannot get it to simultaneously work with my MHL adapter. I understand the GS3 has a different pin layout though for MHL - my phone works with my MHL adapter correctly, but I didn't think it would have any change on the USB OTG. I'll most likely be breaking these apart and start tinkering. My goal is to show people how much of a full desktop-like experience I can provide from my phone, since so many people somehow think a GNex or GS3 are inferior to tablets, just because they're smaller... lol
Good luck finding information out on some kind of MHL/USB OTG setup. I'm just trying to provide any information I can from how my situation works with MHL/OTG, since I'm currently on the quest to achieve this myself.

I'm not really sure why people think they NEED MHL and USB OTG simultaneously to get a "desktop-like experience". You can already accomplish this with just a plain MHL cable and a bluetooth keyboard and mouse as was demonstrated in the Connectivity Demo video on youtube.
Edit: Actually I just remembered about portable hard drives. If you want to hook up a mouse, keyboard AND hard drive I wonder if you can plug all three into a powered USB hub connected to a bluetooth dongle. Hmm...

I'm looking for a dock with USB OTG, charging and MHL. Maybe some day.

I believe this is already capable. Everything I say here is purely speculative, but what I see is that Samsung moved to a 11-pin connector for MHL and the standard 5-pin is no longer functioning. To call it MHL, they probably have to use the same standards for data encoding... but they simply "moved" the pins.
I put "moved" in quotes because of the way in which a standard 4 pin USB cable works (or 5 pin for our case)... you have a +5V, Ground, Data + and Data - (one data to phone, one data from phone, carrying ALL data). Since our phones still sync via 5-pin cables, this means the 5 pins are still "hot" for data like all other phones. I am presuming, that for the 11-pin connector, Samsung simply added a few more data+ and data- connectors (much like having two or three USB ports on a normal computer) but consolidated the ground/5V reference. I could be wrong, but it would make sense.
Lets call the stock 5 pin data connectors (2 wires) USB1. This is where MHL is conventionally sent through and all sycing can be completed through, 5 pin cable or 11 pin cable. If samsung added two additional USB ports to the single connector, lets say MHL is now over USB2 (wires inaccessible to 5 pin connectors). This frees up bandwidth and COM ports on USB1 and USB3 to use for accessories like a USB hard drive and keyboard/mouse. On a 5 pin connector, however, only USB1 is accessible. The Samsung 11pin to 5pin MHL adapter simply moves the data+/- from USB2 to USB1 (standard 5 pin location), so with the adapter you are syncing/exporting video over USB2 on the phone with a standard 5pin cable.
My thinking is such: If you plug in the OEM 11pin MHL adapter, it will also have access to the standard 5pin USB1 connection. Since USB2 is used for MHL, you can then plug any OTG device into the micro USB connector on the MHL adapter to make use of it. The only problem here is power (or lack thereof). By plugging in a USB hub with a discrete power source, plugging this into the MHL adapter, and plugging in the USB device of choice into the HUB, you *SHOULD* be able to get simultaneous data and HDMI. This assumes they put the standard 5 pins to the connector on the side of the MHL adapter and only wired the HDMI to the USB2 area.
Alternatively, you *SHOULD* be able to plug the micro USB cable from the MHL adapter into a computer, and simultaneously be able to sync files while outputting HDMI video. It sort of just comes down to being able to provide power to the MHL adapter on the +5V pin while using the data pins to access the phone. As soon as I have my MHL I'll figure it out, but that could be a bit. If anybody has access to a pinout from a Samsung 11 pin micro USB that would be helpful too.
Again, just dreaming here. I don't know anything about this, but if I was the engineer at Samsung I would choose this over analog outputs like Apple used for their giant connector.

for me at least i already have several keyboards and mice ... none are bluetooth.
I'm looking for the cheapest option available.

I'm just hoping someone releases a cable with 4 plugs:
Male MHL - To Phone Obviously
Female MicroUSB: To plug in charger
Female HDMI - To Display
Female USB - To USB Device
That's all I want... should cost less than $2 to make, just sell it for $20 and I'd be happy.

hi v8bait, are you able to get data thru the micro usb port at the side of the 11-pin mhl adapter? i was thinking of using the motorola lapdock with my s3 thru the mhl adaptor (other then a micro hdmi male connector, the lapdock also has a micro usb male connector that apparently send out power as well as push keyboard/trackpad data upstream) - if it works, we can have an inexpensive "clambook"

Just to recap,
Will this we possible:
Official MHL adapter -> hdmi to monitor.

>OTG cable> Powered USB hub> USB keyboard & mouse.
In other words, the PC Experience with a keyboard and mouse.
Dont really want to spend the money to buy a Bluetooth keyboard and mouse when the USB ones can work just fine (theoretically).

I am also very interested in this exact thing. Using USB devices (multiple ones, e.g. plugging a powered USB hub into S III and then plugging them in) but also putting out S III video to HDMI.
However the other workaround is using AllShare Cast. In fact that is the route I'll likely go, because of the other unique advantages of AllShare Cast (i.e. using it for presentations to screens, etc.)
So: has anyone plugged a powered USB hub into S III and used multiple devices? Such as a keyboard and mouse?
I also want to use this S III more as a computer. the other perfect thing I wish I could buy would be a keyboard case, like the one available for iphone, so I can prop the S III up on a kickstand and use a real mini-QWERTY physical keyboard.

We're in the same boat; i want to use the s3 like a mini computer too. I think it'd be great for business travel, when i dont really need a laptop during the day but want something when i'm back in hotel room. I'd much rather use hotel TV instead of a laptop because that's what i am used to at home... pc hooked to TV.
I've been planning to use the allshare cast dongle too, but they dont seem to be available yet. I was thinking HDMI out with the allshare.. charging with the wireless charging kit and then keyboard and mouse with USB OTG. My logitech unifying receiver for keyboard/mouse works perfectly i just need the wireless charging and allshare dongle to be released.
For what it's worth I tried a powered USB hub and could not get it to work with the s3.

Wait so your saying you tried a (a) powered USB hub with a OTG cable connected to the phone or you tried a (b) powered USB hub connected with a OTG cable to the MHL adapter and then to the phone?
If it was (a) then there are some vids out there of ppl using powered USB hubs.

Very interested in this.,,

I'm puzzled that there aren't any more postings about this kind of stuff. I was expecting the GS3 to be easy to use as a "PC" replacement but it seems no one besides us few wanted to do that ? A simple cable should have done it but I'd even be willing to shell out 40-50$ for a decent dock that would do just that

You are not reading it right.
they want to use the MHL adapter, too.
As far as i can tell, the MHL adapter needs to be in the phone, not a hub. it is all dictated (the output being OTG, or MHL) by the impedance of what is plugged in. It is an either or situation.
Perhaps with a firmware update they MIGHT be able to run both signals and split it.. but i doubt it.

Samsung galaxy S3 OTG for USB 3. hard drives

Hi there,
I have a samsung galaxy S3 (rooted) and have recently purchased OTG cable. The problem is that when I connect s3 with Hitachi Touro (mobile USB 3.0) through OTG cable hard drive does appear in files. I have installed paragon NTFS and stickmount apps but it doesn't seem to connect even though a message keeps appearing "usb connector is connected". Hard drive gives a clicking sound when it is connected with S3 but works perfectly with the computer.
Does anyone know solution to this?
Thanks and regards

I've heard of some people having problems when connected to a usb 3.0 port on their computer and have to connect to a 2.0 port instead. Maybe related?

USB 3.0 I don't think is supported. What I've seen people do is use a 2.0 cable extension with their 3.0 device. As this downgrades it to 2.0 because they should be compatible with 2.0 just won't have the insane speeds as 3.0. Or you can get a USB hub and plug it in that way.

Splatdotsplat is correct. That clicking sound are the heads resetting to the park position. This usually happens when drives are not getting enough power. When the drive spins up it peaks its power consumption and cuts out because there is not enough so the heads reset. Portable or not that is the issue. I have seen this happen with some portable drives on computers (especially larger capacity). A lot of times the solution can be as simple as using a shorter cable. Sometimes it doesn't work.

as stated above, the only way to run external hdd's of any kind is to be sure they're powered, even some thumbdrives will draw more power than the phone can provide and you'll notice your batt life take a steep dive (as did my Galaxy Nexus w/otg on an HP 16gb thumbdrive)
power the drive through a powered hub and you're good to go!

Just to throw in some info. I do agree about the hdd not getting enough power as the cause for the clicking. I have a 500gb hitachi drive that does that if a long usb cable is used. The drive didn't come with a power adapter but instead came with a short usb cable that had two heads. allowing it to draw power from two ports. It also had a port for an adaptor though.
When testing with my Samsung Galaxy sIII It doesn't work unless I have the hd running via external power or have the second usb connector on the cable connected to a charging usb cable. Both options charge the phone while the hd is connected to the phone.
The usb cable with the double ports actually works well for me. I have the first port connected to the otg cable that I made and the second connection connected to a usb extender that is connected to my 2A tablet charger. That way I can charge at the same time.

Hi the problem i basically power as in the amount of current your device requires, i know that the standard specifications of the original 2.0 interface is about max 500mA and 5Vdc per port, in some cases the maximum output current is even smaller due to hardware restrictions, this can lead to difficulties when trying to power something like an external hard drive. Therefore a long cable will also give a problem due to the resistance of the material, because the required voltage level is not high enough.
I do not know if there is a spec sheet containing information about the output capabilities of the usb port, if there is one i recommend using that to match an external hard drives, if you do not want to use an external power supply.
Edit: you could also use an external power bank/battery pack but i seems a bit bulky

i wish there are people who are willing to investigate/try this thing out, it would be awesome to make a portable hard drive works on our S3..

Sure go out and buy me one and i'll test all day..
USB OTG works out of the box for low power devices. I havent seen/read anything stating USB 3.0 works on the S3. I have a 1TB hard drive my brother gave me, its not the newer ones that are ssd so it has a power adapter with it and it works perfectly with my S3. Going to be using it in a few minutes to back up my internal SD.

So guys I have the GT-I9300 ( Galaxy S3 ) and I have 1 TB WD My Passport
I'm plannig to buy the OTG piece ! so as of now is possible to connect the hardrive to the phone or not yet !?

Is there even a driver and an app to do such a thing? As I see it the USB port is configured as an external storage device to connect to a computer not the other way around. What you are doing is connecting two storage devices together. There's no way I would ever connect anything to my phones USB port that requires power. If I were to, it would be through a powered hub.

USB 3.0 I don't think is supported. What I've seen people do is use a 2.0 cable extension with their 3.0 device. As this downgrades it to 2.0 because they should be compatible with 2.0 just won't have the insane speeds as 3.0. Or you can get a USB hub and plug it in that way.

I have read that you connected your S3 with external powered HDD. I bought yesterday the genuine samsung OTG cable and it is working only with memory stick and joystick controller. Don't know why it is not working with my external powered HDD - 500 GB WD. Any ideea ? My S3 is not rooted.
Thanks,

No, nobody is going to have a recommendation for a powered USB hub.
It's a trivial, generic, piece of kit you buy nearly anywhere for under US$10 (unless you're a complete sucker.) Just make sure whatever you get *includes* a power supply.
Get one in the shape of a person, or a kitty cat, or a Tardis, whatever thrills you.

that's not quite accurate. when you plug your phone into your PC, the drivers that you installed will see your phone as a usb device (or media device) and allow you to use your phone as such
an OTG (on-the-go) cable allows you to connect a storage device to your phone, such as a thumb drive or external hard drive (powered or not) and then your phone acts like your PC and uses that device as storage

I can confirm that in my case forcing my ADATA HV610 1 TB disk to USB 2.0 mode worked. The trick is to use a standard micro-USB cable (e.g. the one that comes with your charger) instead of the standard cable that comes with the HDD.
More detail:
The common USB 3 cable which comes with most new HDDs uses USB 3.0 Micro-B plug which, in practice, is a micro-USB with a "half-micro-USB" next to it. The part most people don't know is that you can use a common micro-USB cable (as the one from your charger) to connect your HDD to your PC (or other device) with the cost of loss of USB 3.0 compatibility. Which, in our case, is what we need, as this switch makes the HDD less power-hungry.
Post a comment if it works for other hard drives too (I think WD also use Micro-B connectors for their USB 3.0 Passports)

is there a usb otg cable that'll power the phone and allow usb connections?

i like to use my nexus 5/7 to connect to my computer at home through VNC but it draws up quite a bit of power. Is it possible to have a OTG cable that'll connect to the MicroUSB port of the phone and then two cables come out, one that has female MicroUSB port to charge the phone, and a second cable that's a female USB port so I can connect a USB mouse to?
Thanks

I have not tried this myself but read on other devices that OTG Y cables will do what your asking.

Be warned that sometimes the specific device will not support concurrent charging. The cable link above specifically mentions the Nexus 7. Read the reviews.

I have that cable, it does charge the phone but stick doesn't get mounted. I haven't tried to make it work or anything because I don't use it.
