OTG doesn't work

I tried to pair wired mouse, wireless mouse and a gamepad with OTG cable and even with mini-USB to USB.
Nothng's working and it doesn't even read it.
Any ideas why and what should I do?

see
Issue 22038: USB OTG doesn't work at all.

ICS supports it but the Galaxy Nexus does not. there is a mod in the development section that allows USB devices to work.

you mean this:

?

Possible to get midi input to our phones? [YES]

Is there a way to get midi input recognized on our phones? On my pc I use the rock band 3 keytar connected via a midi to usb adapter and I can do midi playback.
Is there a way to do this on our phones via an otg cable?
EDIT: got it done! check my post below.

it works beautifully and way easier than I expected.
connected my otg cable and the phone said usb connector connected (since when is this a thing!?), plugged in the midi-usb adapter to the otg cable and right away it prompted me to open with the software I linked above and another midi software I had installed.
and bam, it was working. I messed around a bit to find the better settings for my keytar, but this thing works. over Bluetooth and with the headphone plug. there's a little bit of lag over Bluetooth but for my uses I wanted it straight to the speaker so i'm using the stereo cable. now I don't need a pc to get sound out of the keytar.
mark this as one more day i'm amazed at what my phone can do.
by the way, it functions as a synth using the software I mentioned above, so I can play harpsichord, organ, piano, etc. and the sound keeps on playing even with the screen off.
happy camper = me.

Looks like you had some luck... Wondering if you can help me?
I am trying to make my Android, Huawei p20 Pro, accept a MIDI signal via USB too.
I have an OTG adapter, and have tested 2 OTG adapters and 2 cords.
All work into my PC (even via an USB type-C to standard USB adaptor )
The issue seems to be that I cannot select the USB in type to be MIDI.
I have also experienced that on another Samsung Galaxy S10
I have tried opening developer settings and changing the setting "Disable USB Audio Routing" ON as per https://help.joytunes.com/en/articles/2636638-troubleshoot-midi-on-your-android-device
I have tried using it with 3 apps that accept MIDI.
Simple Piano by Joy Tunes, FlowKey and USB MIDI Monitor
Any ideas?
Environment
Huawei p20 Pro
Model: CLT-L29
Build: 9.1.0.381 (C782E11R1P11)

[Q] Nexus 7 (2013) logitech wireless drivers

I have a Nexus 7, rooted, running the stock KitKat. I have tried connecting an OTG cable with a logitech unifying receiver. I have a K360 keyboard and a T620 mouse paired with the receiver. When I use the OTG cable on my HTC One X, as well as a Galaxy S3, both keyboard and mouse are recognized and work fine. On my Nexus, however, they are not recognized. I ran OTG Troubleshooter and it confirmed that my cable was being detected, but said there were no drivers in Linux, nor in Android, for the receiver. I have done many a search but have been unable to find how to solve this.
How can I fix this driver issue? Will any of the custom kernels here have a fix for this? Any help would be much appreciated. Thank you.

There's a kernel that fixes the same problem on the Nexus 10. As a noob, I have no idea if you could use the same kernel on the N7.2 (2013).
I have the 2012 N7 and the 2013 N7, and my logitech unifying keyboard receiver works on the 2012 N7, not on the 2013 N7.
There's more to it than just a missing driver. People have tried 2012 versions of Jelly Bean on the N7.2 and still couldn't get it to work.
This is a bug, and Google needs to fix it.

There is no ROMs/kernels with unifying drivers?

[Q] Fire TV XBox 360 Wireless Receiver Third Party

Hallo everyone,
I'm new in this forum and I hope I am right here.
So the Fire TV is new in Germany and I preordered it.
It would be fine if I will be able to use my wireless Xbox 360 Controller with it.
I have read that it is possible to use the original wireless receiver for PC.
But what's about the remake from it (the version from China)? For PC I have to install the drivers manually.
Is it possible to use? Has somebody tried it?
For example like the "White PC USB Gaming Receiver Adapter White For Xbox 360 Wireless Controller" on amazon.com
Sorry I'm not allowed to post links.
Thanks!

Hello
Yes, i have one from ebay (chinese clone) and it works fine. Lights in the controller doesn´t light up as usually but that happens with the official receiver also.

Hey,
I'm using a knockoff chinese receiver. I got mine on amazon for about 13 USD and it works great. It can be a little tricky to configure the controls with Mupen 64 or whatever emulator you are using, and the 'x' home key always takes you back to the games section of the kftv launcher (despite having xbmc set as the launcher, for example), but it works in game just fine.
Let me know if you have any questions- I'd be happy to help.

Can you connect more than one Controller on that adapter? I read, that 4 Controller + 4 headsets are possible with this adapter (on a PC). Whould be nice for multiplayer games...
Gesendet von meinem GT-I9295 mit Tapatalk

I haven't tried headsets, but I've used at least two controllers at once, and I also understand up to 4 per receiver works (theoretically more receivers = more players, but I'm not buying another one to test that theory).

How to hook up third party controllers correctly
I was searching the web up and down in order to get my third party controller (china) to work without a solution. Actually it was easier than I thought:
- connect the dongle
- restart the Fire TV (5 sec hold of Play+Big Button)
- press X on controller
The controller doesn't stop blinking but if you are able to navigate through menus everything worked well.

I bought this receiver from amazon (www (dot) ebay (dot) com/itm/271687378076?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and it's not working when I plug it into the Fire TV. I believe the receiver works though because when I plugged it into my mac and I was able to see all the keys responding using 360Controller.
Everybody seems to have minimal issues connecting controllers to their Fire TV. Any ideas?
(Sorry, I don't have enough posts to post links.)

I'm sorry, but it'd be tough to replicate the issue without a device to test with. That receiver looks identical to the one I purchased, but I don't know if it is actually the same on the inside.
I don't know about on OSX, but I found that I could pair the xbox controller with the receiver on my windows PC (using the generic driver). Once I had paired on Windows, I could plug the adapter into anything running android and it would work just fine.
That's the first place I would start- try pairing a controller and making it work on a machine running Windows or OSX or whatever is 'supposed' to work. That way, you can at least tell if the hardware is bad. If you are able to pair and use it on one of those machines, plug it into your Fire TV and use the same controller and see if it recognizes it.
If it works on OSX or Windows but not on the Fire TV, I don't know what to tell you. Maybe pick up a USB OTG adapter and see if you can get it running on another android system. I haven't found a phone / tablet yet that hasn't been plug and play with the adapter.
Lastly, and this is unlikely, it could be that you are running a USB hub that isn't able to provide sufficient power. If that is the case, unplug all other USB devices and test it in the port. If it works there, the hub / draw of other devices is your problem. I'd recommend getting a powered USB hub in that case.

Thanks for the suggestions but I don't think the adapter will work with the Fire TV. I'm not using a hub anywhere in the setup.
I can pair the controller to a Windows machine using the adapter and the generic driver. I'm able to see the computer register all the inputs using the joy.cpl (app?) in Windows. When I plug the adapter into the Fire TV afterwards, I still can't control anything with the controller. Does the ADB debugging switch make a difference? I have the adb over usb set to OFF.
What's an USB OTG and where can I get one? What adapter did you pick up that worked? It might be better if I just picked up the same one instead of troubleshooting this one. Open to any other ideas though.

I'm still not convinced the device is not malfunctioning. Did you actually connect and use a controller to control the PC? It could be that the device is connecting and sending some information, but the part that actually connects to the controller is broken. On Windows, you can just download the driver and install it as per these instructions: https://krisrowland.wordpress.com/2...eless-controller-adapter-in-windows-7-64-bit/
I'm pretty sure this is the controller I bought. Like I said, it looks the same as yours. I'm confident you just got a bad unit.

I had one question:
-Does the rumble function work? (The vibration)

It's been a while since I've actually used it, but if I remember right it does work if you map it properly in the emulator you are using. For example, Mupen 64 has support for rumble packs, and I'm about 80% certain it works.

hi mate did you ever get this working, i have the same issue, bought a cheap receiver from ebay. hooked it up to laptop, installed driver, worked fine. connect to fire tv, nothing!
ARGH!!!!

The cheap china clones just making problems with Android aka FireTV. That's what I heard.
But the original adapter makes me sometimes Problems too. Sometimes the Box Start in security Mode (grey written in the left corner of the screen) or had to replug them After Start to let the Box recognice the adapter again.
I bought two very great Bluetooth Controller from "mi". Really nice. Like Xbox 360 Controller. You can buy it cheap @ allbuy.com.

I got it working!!!! Make sure all developer options are turned off in settings.

Hi there, I'm having the same issue here.
HARDWARE: - FireTV 2.0
- xbox 360 wireless chinadapter
- xbox 360 wireless controller
I've turned off the dev settings on my firetv, connected the 360 controller via my chinadapter to my pc to verify that it's paired and working. Plugged my adapter into my firetv. Restarted firetv. Pressed the silver X button, the blue x button, the ))) connect button... Still nothing. I've gone into the "Add a new controller" area (where it tries to establish connectivity) and tried everything I can think of. I was really excited about this and am kinda bummed. Not wanting to buy extra controllers really.
- something noone else has mentioned running into - the firetv seems to crash or reset itself when I push the ))) connect button on the chinadapter receiver. . . weird. . .

UPDATE:
I got it to interact randomly. Unfortunately it was unacceptably buggy. Crashing games, not recognizing inputs and, well, everything that might be awful about a controller. So I guess I'm looking into cheap bluetooth controllers. def not spending $50 on Amazons controller to play freaking android games lol let alone games in the amazon app store. Thanks for the thread and any advice on getting it to work properly you may have discovered.

I am having the issue of not being able to connect my 360 controller via the Chinese adapter to the fire tv....I have got it working in windows but it wont connect on the fire tv. I have disabled developer options restarted the fire tv and hit the x button to try to connect but I get nothing.

Can't use USB in car

I had the Nexus 6P (with Android 7) and plugging it into the USB worked with my 2011 Camaro (it is not Android Auto, the Head-unit basically will see the phone as a USB Storage device, mount it, index the files, and I could then use my car's controls to search, change tracks, etc).
I broke my phone and turn it in on warranty, and end up getting the Pixel XL as replacement, and upgrade it to Android 8.
Now when I plug it into my car, I get a "No supported media found" message on my car's display. I have tried with and without USB Debugging, going into the the developer options and changing the "Select USB Configuration" to MTP, Audio Source and still the same. I would also have this issue with Samsung phones, and could never get them to work.
I am not sure if this is an issue with Pixel's, or with the Android 8 update, since my Nexus 6P with Android 7 worked fine

you need to use the otg adapter that came with it

So I have to get a standard USB-USB cable to connect the adapter to my car?
I thought this adapter added functionality, so my phone can mount drives, not the other way around? Doesn't make since that something that has worked so well on the past 3 phones (except for Samsung for whatever reason) now no longer works without another piece of hardware. Not what I would call progress

So I ordered another cable and am using my OTG adapter, and it still does not work.
