Ok, so has anyone else had problems with this..
when you plug in an OTG connected usb device (i have the same problem with usb drives and midi controllers so far) and in the notification bar pull down it will say charging usb device, and when you choose to switch it to something else, like transfer files or connect a midi device, it just goes right back to charging the device after changing it for a few seconds or until you tap the screen or check it again.
This has completely stopped me from being able to connect a midi device, and causes the usb drives to get hot, although I can still transfer files in an 3rd party file manager, but the notification bar will never stay in tranfer mode, and it has never gone into midi mode at all.
This is not an issue with my OTG adapter, as I also have the same problems with borrowed adapters, as well as using DEX. In fact in dex, if I plug in a usb drive and switch to transfer files mode it will crash. Has anyone else experienced these problems? Are any of these apps for OTG management in the play store useful for this? They seem to be useless based on the reviews except for testing a UTG adapter. Thanks!
btw I don't have root, my note 8 is fully updated to BQLA version.
Hi, check the battery! If internal resistance goes up so does noise.
Check the cable and connector on the phone as well.

Is it possible to use the micro USB audio connector for audio? After rooting, the audio application of the android does not recognize the mp3 files to play. Why not let it do so?
I think that would require USB host mode like on the Samsung galaxy. I think that means needing extra hardware doesn't it? -otherwise I would expect every phone to be capable of it
edit: It is possible but you can fry stuff. Info on NookColor forum
USB host = great possible enhancement?
I wanted to post to proper thread, however I am new here I was not allowed to post on developers forum. So I hope that this post will still somehow find its way there. It also includes your original question.
Since some USB features are now claimed to be working, I wanted to ask directly poping out questions:
http://forum.xda-developers.com/showthread.php?p=21669750
Is it possible to...
1.) disable on-screen keyboard while using USB one?
2.) connect USB soundcard like: http://www.usbgear.com/computer_cable_details.cfm?sku=USBG-X2X&cats=121&catid=121%2C136%2C134
To allow listening mp3, Skype calls.... ?
3.) connect USB Ethernet card like: http://www.usbgear.com/205528.html
4.) to connect other cool usb stuff like: GSM, printers ... whatever
thanks you developer guys, I hope I'll once manage some time to learn more about the system and developement so that I could contribute too !
thanks to androind and nook simple touch creators!

Currently the answer to all of the above is no
The USB host mode patch was done for a specific project (USB keyboard support) and while I have been spending some time playing around with Bluetooth I'm not aware of any other dev(s) working on expanding this atm.
Stuff like audio, networking and Bluetooth requires _a_lot_ more than just the kernel accepting to communicate with the device.
thats shame. allowed skype calls would be great
Skype calls are working on my nook with OTG + USB audio card on usb host mode. But it is a bit difficult ))).
To update these older posts:
Yes, it is possible to disable the soft keyboard when using a USB keyboard.
See NullKbd in the signature.
Yes, Skype works fine.

Where is the difficulty?
Do a logcat and look for overruns and errors.
There were a few mods done to make Skype work.
so an external usb sound card is working?
Yes, an external USB audio adapter can work.
As a portable solution it's a bit cumbersome.
I don't know what current they usually draw, but my cheapy one draws 75 mA.
A desktop solution with powered hub (charging the Nook), a USB adapter and speakers works fine.
Would USB headphones work directly on that port? I have USB OTG cable and some USB sound card somewhere so I can check with regular 3.5mm jack headphones without trouble when I find some time to do it but I just wonder if anyone tried USB headphones on it and what they think of it. Is it worth of a hassle to buy one for NST?
Some USB devices use a multiplexor on the USB micro connector and can send actual analog audio down the connector.
Many Androids support USB host mode and can support an audio USB adapter, including the ones that go for < $10.
The NST (earlier Nooks with OMAP processors) don't have complete software support for USB host mode but can be coerced into working.
The Glows (later Nooks with IMX processor) don't have complete software or hardware support for USB host mode but can be coerced into working.
The Glow4 (7.8") has audio.
Hi,
Can somebody verify otg connection is working for this tablet?
I tried my cable but it does not turn the device into usb host mode.
A quick test with a usb host testing app showed that this tablet has no usb host capabilities. Shame.
BS - of course this tablet has USB host functionality.
Via the usual OTG adaptor you can connect the usual USB sticks, hard drives (with own power supply), mice, keyboards etc.
It has even a special feature (can be activated in audio settings) for connecting a USB DAC for high-quality sound / recording.
Yes, it works w/o problems

Cool, looks like that test app isn't very accurate then.
This is the result it came up with:
If @datalkingx means with OTG connection to connect USB Flash Drive, Keyboard, etc. then it works, if he means something else then I don't know

Not all devices works some memory card reader don't work.
I've been trying to find information about this on the web but I've failed to do so.
I bought a Kingston Micro duo USB C 3.0 and it worked a couple of times (I had to manually change to MTP) using the USB C connector straight on my S9+.
I've been trying to get it working again on my phone with no luck. Everytime I connect the USB C end on my phone, it will show on the notification tray "Usb charging device" and "USB connector connected", this last one will disappear in a matter of seconds.
I've set the default to be MTP using Developer Options and even select MTP for the device once it connects, but it just reverts its status.
I know for a fact the USB C end works because I can connect it to my computer (Windows and MacOS) and I've tried formatting it using a lot of different formats, still when I connect the USB C to the device it doesn't read it.
I managed to get the drive working using my USB C dongle (Which has 2 USB A 3.0, but no power passthrough) and connecting the USB A side to it and my phone recognized the drive instantly! So I formatted the drive using my phone, connected the USB C end on the device and it doesn't recognize it.
It seems it's just a bug on the Samsung device or something. I guess Samsung is moving towards USB C but they are not thinking on all the stuff you can connect.
I found this link https://us.community.samsung.com/t5...g-defaults-to-charge-other-device/td-p/183539 and this other https://forum.xda-developers.com/galaxy-note-8/help/note-8-usb-otg-t3680207 but so far no solution.
Edit:
I just tested my drive with an S8 and it worked without issues (the USB C end) and was able to test it on another S9's and they don't recognize it.
Mine works without issue. Not sure what's happening with yours sadly. Edit - mine's the Micro Duo 3C, but I can't imagine there'd be much difference.
Same here. Today I had hard times getting to work my USB stick and a default dongle. Every time I inserted the dongle the notification goes "USB charging device" and changing to "transfer files" doesn't change anything. Playing a bit made a 32gb stick visible in a file manager (namely x-plore) and I was able to transfer files to it. But no PC recognizes the stick so far...
Hello all,
I am currently trying to connect my wired Xbox 360 Controller to my Huawei MediaPad M5 Pro. I am using a USB-A female to Micro-USB OTG cable, with a female Micro-USB to USB-C converter for my Huawei's input jack. The Xbox 360 Controller plugs directly into the female USB side of the OTG cable. Like the YouTube videos suggest, you are supposed to simply connect the controller, and it will work. However, in my case, the controller will be supplied power, but not detected. When I scroll down to see notifications, it shows that power is being supplied to a USB device. When I clicked the touch for more options button, reverse charging was selected, and clicking any other option would bring it back to reverse charging. No app was detecting any movement of the controller, and the "Easy OTG Checker" app that I found in the app store detected it as Unknown. I then went to settings, but the USB section of the Device Connections tab was grayed out, and showed the text "Disconnected." After doing some research, I tried to fix the problem by turning on USB Debugging in the developer tools section(I had to turn on "Allow ADB Debugging in charge mode only" to do so), but it still wasn't detected, and the USB tab was still the grayed out and "Disconnected." I also tried connecting the controller in the Huawei's "Safe Mode", in case some app or security system wasn't allowing it. This didn't work either. Nobody else I've found on the internet has this same issue. Any Ideas how to fix this?
Thanks!
Extra Info:
Android Version - 8.0.0
The Xbox controller had a loose cable once, but this was mostly fixed with a cable patch, only leaving one button to be faulty every once in a while. Worked fine though on my computer.
Dang this forum isn't responsive at all XD
I have the same issue, you are not alone. Its a while ago that i tried to find a solution but didnt...
Hey, the phone is sold as a phone\power bank combo, and when I connect anything to the usb port, it tries to charge it. I think that may be why I usb to 3.5mm adapters dont work. when connecting usb drives or a keyboard nothing happeneds, so I decided to try to enable otg.
I tried adding the android.hardware.usb.host.xml and editing the handheld_core_hardware.xml, I also added rp.usb_host = 1 to the build.prop but nothing changed.
thought maybe if I disable the usb charging it will behave normaly, but I have no idea if that could be done.
any ideas?
