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

That does work, and works a treat I might add.

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

One Plus 3T OTG and Micro USB to type C adaptors/ Oneplus3t OTG capabilities

I had some initial difficulty getting a micro usb OTG cable working, I ended up testing a few and thought I would share in case it saves anyone else some time or money.
if anyone else has adapters they've tried feel free to list them
I actually haven't tried a straight USB type C OTG cable yet, all have been micro USB OTG units with a micro USB to type C converter since I already had so many lying around.
First off I should mention not all micro usb to USB type C converters support OTG.
this Meenova one does and works with the oneplus 3t: https://www.amazon.com/gp/product/B018G6IK7E/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
with that converter pretty much any OTG adapter will work.
Charging also works.
This micro USB OTG adaptor is nice because its so low profile.
I tested it with a flash drive and it works fine with the Meenova adapter listed above.
https://www.amazon.com/gp/product/B0196FG4DG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
This Samsung adapter also works well with the Meenova adapter, it has quite a few features which I tested on the Oneplus 3t, its expensive though so unless you have a Samsung tablet as well its not likely to be worth it for most people:
built in features:
two USB ports
Ethernet port
Charging port for simultaneous charging and OTG
On the Oneplus 3t both charging and OTG work fine but not at the same time.
whichever you plug in first is what it will use until you unplug and re-plug in the adapter.
That being said my understanding is that this is likely just a kernel limitation, it was the same way on the nexus 7 and a custom kernel enabled the simultaneous charging.
I'm not sure how useful that would be on a phone but I thought I would mention it.
Both USB ports work simultaneously, I connected two flash drives and both were picked up by the phone right away.
I wasn't able to get the Ethernet port working, or at least there was no indicator that it was working (My samsung tablet gives a notification that the Ethernet is plugged in but Samsung may have added that, I'm not sure) I'll play with it some more later.
Adaptor link: https://www.amazon.com/gp/product/B00J2N0GB4/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1
and lastly I tried this micro USB to type c adapter and charging works but OTG does not:
https://www.amazon.com/gp/product/B0191FRCAA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Thanks for your post about OTG adapters. Do you have any updates on this issue? I'm looking for possible adapters but cannot find any.
The Meenova adapter is not available in Europe and also seems not to be available from Amazon.com anymore. I can also disadvise from Anker USB adapter because it doesn't work.
What I'm looking for is an USB typ-C to microUSB adapter for audio output via USB.

Anker adapter supports dash charge (works with oppo vooc power bank). I am trying OTG now, but I have some cheap OTG dongle (https://www.aliexpress.com/item/5pc...G-adapter-for-HTC-for-Samsung/1734417126.html) and I am not sure if it works at all Anyway OTG via Anker is not working for me at this moment.

USB OTG Poorly Supported

USB-C to USB-A OTG Cable -
Not able to power a simple external USB MSata Drive or External USB HDD - I plug these drives into a LG V10 or a Galaxy S8 and work perfectly fine. What gives? I have only able to get a flash drive to work.
Any known work a rounds? Anyone else try this?
Thanks,

No answers for this?

I tried this just now and am shocked it doesn't work either.

I wonder if OTG power support was removed due to the decrease in battery size? Has anyone tried OTG "audio output", say through a device like the audioquest dragonfly, to see if that works??

I don't think so, since the notification that pops up when I connect 32 GB ADATA USB 3.0 flash drive -> USB 2.0 A female to micro-B male OTG cable -> micro-B female to USB-C male adapter -> Z2F says the Z2F is providing power to the connected device. The problem is you can't do anything else BUT that.

I'm wondering this myself. The fact that the Z2F outputs analog audio over USB-C leads to me to believe that it isn't fully USB-compliant.* Both the HTC U11 and Google Pixel 2 output digital audio, which, based on Google's crowing about USB-PD and the existence of devices like the dragonfly, appears to be the right way to do things (albeit with the tradeoff of more expensive audio peripherals, which much now have their own onboard decoding hardware.)
*Can anyone with knowledge of the USB spec comment on this?
BTW, I started a support thread about this at the official forum, where it's received several replies and suggestions from a mod. Kindly chime in there too so Lenovo can see this is a real issue they need to address.

So based on this Motorola mod post and the OP's statement that USB-C flash drives work, the Z2F and Z have the same (lack of? LOL) OTG functionality. The Moto Z subreddit has a pretty extensive thread about Moto Z DAC functionality; it appears the Dragonfly is supported, among others.

Interesting development: another Motorola Forms mod now says powered USB hubs are rumored to work. We're making progress, folks.

Okay fellas,
I so far have been able to get certain drives to work and others not! I have tried 2 different USB-C to USB-A cables and get the same results, 1st ones an HP cable and 2nds an Anker USB-C to USB 3.1 Adapter
https://www.amazon.com/gp/product/B01COOQIKU/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have been able to get a 256gb M2Sata Drive, 500gb WD Mypassport, and a 2TB Mypassport to read.
I also have a 256gb MSata Drive that will not power up or read without using a powered usb hub. However the Msata Drive will read without an added powered HUB. On the Samsung and LG Devices.
Only thing I can think of is that certain drives have higher amperage that the Moto Z2 simply cannot push through its USB-C Port.

Good to know it isn't just me experiencing broken USB OTG support.
I've got a PS3, PS4, and Xbox one controller I hook up with USB OTG. Normally it's as simple as plug n play and I'm good to go. However, that doesn't seem to be the case here. I can still pair the PS3/4 controllers in sixaxis just fine and get power to the PS3/4 and Xbox one controllers. And yes, that bit about supply power to device rather than transfer and you can't pick something else, happens to me too. Sometimes I can plug my thumb drive in and I can explore through the storage file explorer, but I usually have better luck with an app called X-Plore.
This one time I even had said thumb drive take out my entire OS to the point where I had to use that June ROM to reset me back to start. Spoiler alert: I kept getting "Android.process.acore keeps crashing" over and over; various other apps kept crashing as well.
On a side note if I can at least get PS3/4 controllers to work for a long time within say, sixaxis (or similar) I'd appreciate any tips. Otherwise I either gotta wait for this to be solved in a future upgrade, future sixaxis, or when we start getting custom ROMs..

This is excellent information, thanks a lot man.

So FYI I tried the Anker adapter @XE-Cherokee linked to and it worked perfectly. That seems to be the solution for now.

Appreciate the heads up, to confirm this adapter works perfect with my external drives, and as an added plus, also my external DAP/amps for audio playback.

The latest Neutron and USB Audio Player Pro will output bitperfect (non upsampled) audio perfectly to both my portable DAC/amp units.
USB Audio Player pro, has the benefit that you can stream tidal native, bitperfect if you have an acct. Which is awesome imo. Tidal still buffers SUPER slow on this device though. So I'd recommended only offline use (which you CANT do with USB audio player pro due to licensing)
I would also add that I get some scratchiness out of the stock USB C to 3.5mm dongle that came with the phone. I thought it was the port being "dirty",. but I have NO NOISE out of the USB audio output using the Anker otg cable. Maybe Anker makes a USB c to 3.5mm adapter.

One tip for getting USB powered OTG drives to work is to use as short a USB cable as possible. Like get a good quality 1ft USB cable. I used to have a similar problem with using an external drive on a Wii and found that a 1ft cable would allow me to use 2 different drives that otherwise would not work with a 6ft cable.

It worked!
I used a USB 2.0/type C adapter that cames with s8 and instead the original USB 3.0 cable, put another adapter, and transferred files with Total Commander.

On this subject but kinda off topic. How are you all getting your drives mounted? I cannot mount NTFS or fat32 drives. Only ext3/4 drives.

Yep, basically you created a 2 inch cable. LOL.
In essence, many USB powered hard drives approach the power limit of what the USB port can output. Power drops over the length of a USB cable, so longer cables may not provide sufficient power for the drive to function correctly. Better quality cables usually have less power drop, though it is not a guarantee.
Unfortunately most USB powered drives do not list their power requirements. The only way to really tell is to open the case for the USB drive and look at the hard drive inside it to find how many amps it draws. For the best compatibility you want the lowest amps.

I don't think that's otg power issue. I think it is locked by Moto becuase they want you to use their add-on devices. I have a wifi camera it doesn't work either, But it works in my all other phones

Just because an add-on device works for one USB OTG implementation doesn't mean that it works on all USB OTG implementations. There is an enumeration of what devices and types are accepted. I have tested USB OTG audio microphones, USB OTG audio speakers, USB OTG Headphones, USB OTG Ethernet, USB OTG Keyboards, USB OTG Flash drives and those device types work. If there is no device driver for the device attached then it would need to be supplied by an app. OTG power drain is definitely an issue and is mentioned in the OTG specifications.

That's what I tried to say. It is locked by Moto. They want you to use their add-on mod. I have tried extrenal usb c endoscope camera, wifi endoscope camera, lg wireleas projector, Samsung projector. None of them work with Moto. However, the same apps work in all other phones. It is clear to see, it is not all otg related all the time or driver which provided by app. It could be just locked by Moto, becuase they want use to use their mod add-on. People who rooted the phone was able to turn on those supports.

I use a Belkin OTG adapter, it worked but it was extremely picky. The Built in files app only picked up my HDD if it was either Fat32 or exfat. But the ES File Explorer app only picked up NTFS.

[Q] looking for a OTG cable for my S3

Hello -
I have been looking all over for a cable that will work for what I am trying to do but I just can't find exactly what I need. Maybe I am looking for the wrong cable type?
I am trying to plug my Seagate Portable 4TB SS HDD. into my Rooted Galaxy Tab S3 SM-T820. I dont really understand what cable type
I need when I look at my Tab. I guess it is a Mini USB Type 3.0 - C ?? The only cable that I have that fits it is the one that came with the tab.
Am I looking for a Mini USB C 3.0 ( adapter to a ) Solid State USB 3.0 ? ? ? - Please look at the picture to see what type of connection my HDD has.
It is 2 connections in 1 . I assume part of the cable is for power and the other side of the cable is the transfer side. ?
So I guess my main question is: What cable do I need ?? ALSO ... If I cant hook up to the Portable SS HDD, then how about just hooking up my Tab to my 3.0 USB slot
on my desktop?
Thank you !!

You have three concerns here.
1. Power.
2. Cable.
3. Compatibility.
*If* the tablet can power the external drive, and the external drive is compatible, a usb c to micro usb 3.0 cable will be all you need.
If the tablet and the drive are compatible and the tablet can't provide enough power to he drive, you will need a powered hub...tablet connects to the hub, the hub connects to power and the external drive.
as far as compatibility, you are *probably* fine, as long as the drive is formatted FAT or FAT32. If it's NTFS or something besides EXT, you are most likely hosed.
Good Luck!

Buy Type C adapters that are designed for Mac books. they work great with Tab S3. Just make sure it is USB 3.0 or above.

USB OTG support

Hi, may i know if there is USB OTG support for Note 10+? I cannot use OTG on my device, is it hardware problem? or software problem?

This thread prompted me to check the OTG for myself, I have USB 3.0 dongle that I haven't used for a while - all is good, it works.
This dongle doesn't require additional, supporting apps, I just plugged it in and it showed as a drive right on.

I dont't know if it qualifies an OTG device, but I used my Flir cam with the Note 10+ and it works. Since it is a micro usb connection, I had to get a micro to USB C adapter and it specifically requires an OTG rated or compatible connector. The regular micro usb to USB C adapters don't work.

For a Flir One? I was specifically talking about attaching a Flir. It is a specific requirement to make it connect to a USB C device.
For data transfer, charging, or other connections, I can use any micro usb to C adapter.

Shouldn't make any difference, it's OS ability to do these things. In my case I just plug it into USB and it shows in "My files" app.
How is your pendrive formatted, is it FAT32? My microSD drives for Android are all formatted as FAT32 I even found a way to format 64 and 126GB to FAT32. Can't use it for full movies though. If you have another microSD around try to format it as FAT32 and see if that works.
Also, see if it helps when you change the default settings for connected USB devices.
