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.
if i can connect the PS3 controller to my phone with bluetooth while the phone is connected to my PC with usb cable,
is there any way i can use the controller on my PC trough my phone bluetooth?
(like making my phone a bluetooth usb dongle).
it sounds possible, but i cant find any info about it.
btw im using samsung galaxy s3
bump....
its kinda good idea...
cant find anything related on web
OK, I know this is a very basic question, but with Google I can't find a specific answer.
When I go to connect my S4 to my computer via a USB hub, the computer doesn't see the phone at all. However, if I disconnect the hub from the computer and plug the S4 directly into the same USB port on my computer that the hub was connected to, it works (i.e. the computer sees the phone).
I know the first thought is that the hub is bad, but I can plug in a thumb drive to the USB hub and the computer sees it fine.
FWIW - it's not an externally powered USB hub - it only plugs into the USB port on the back of my computer. I don't know if that has anything to do with it (although I still wouldn't understand why everything works fine going direct from the phone to the USB port on my computer).
Thanks in advance...
I got a s3 with a broken screen completely shattered, no light, no touch response etc. but the sounds and notification lights work, i can connect with usb as a media device i can access internal sd...
my question is is there any way i can mirror the screen to my computer via usb without doing anything on the phone because as i said the screen completely gone, maybe with adb or something?? i'm interested in how i can control the phone through the pc, like how asus pc link does it, if anyone can give me any pointers on further reading it would be much appreciated... i don't even know if samsung has such a function..
also i would like it if whenever i connect the usb the phone screen would pop up on the pc, are there any tools that do this?
ps: i heard about hdmi adapter but it doesnt let you control or click on the screen right?
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.
