Hi everyone.
I have a Usb midi keyboard (novation launchkey mini) that doesn't need any driver to work (usb class-compliant), but I cannot make it work properly. I'm using the recommended app (Rd4 by mikrosonic) that does work with other tablets. The keyboard connects with the app successfully, if I press any key I get the corresponding keypress on the app, but I don't have any sound output. I tried using other apps, but I have the same issue with all of them. I don't know if my tablet is defective, if it is a Sony's ROM problem, or if it has to do something with the hardware.
Do you have any idea what the problem might be? The only thing I can think of is that the tablet is trying to output the sound over the usb device but I haven't been able to change that (or if I select that option it doesn't do anything). I'll try to root it this weekend, but I'm not sure if it will help.
I know it is kind of specific, but I'm hoping you can help me.
Thanks!

Yesterday i was chatting away on the phone , and realized i wanted a solution that would let me control the phone from the pc.
I installed droidvnc server but somehow it doesn't work, it automatically stops the server as soon as you try to connect to it.
So today i thought of another solution (besides buying a bluetooth keyboard), which is to emulate a bluetooth keyboard in software installed to the pc.
I have searched this and apparently it isn't easy to do. I have a bluetooth dongle on my windows laptop, but this isn't enough since i would need to emulate the proper hid profile.
Is this possible? Or do you know of another solution?
This sounds like some Xzibit 'Pimp my Atrix' type mod. Yo dawg! I heard you like to input text on your device while your talking on it but cant see; So I installed an emulator on your laptop keyboard so now you can type on your laptop while you type on your phone while you talk on your phone but cant see!

Dude WTF. i'm not looking for a headset.
I want to use my laptop's keyboard as the phone's keyboard over bluetooth.
In linux, there's a program called hidclient that seems to do this. I want to do this from windows. Basically i want a virtual bluetooth keyboard.
Well I was trying to make you laugh but I guess no luck..
Have you tried the "Phone Portal" app in your app drawer? It will allow you to send sms and such via your computers keyboard.
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.
I'd like to figure out how to connect my Yamaha MIDI keyboard to my Asus tf101 tablet for recording via hardwired USB.
I've scoured the web looking for an app or solution to this and have come up generally blank, I've tried all the free midi controller apps, but they only seem to support Wifi or Bluetooth, which my keyboard is unable to do.
I'd like to eliminate my computer as a middleman (If I'm at my computer I'd just use that) and be able to use my tablet to record on the go!
Any ideas/thoughts/help/wisdom/proverbs/ninjas would be greatly appreciated
Device Info:
ASUS Transformer tf101 running
ICS 4.0.3 Rooted
I have the dock with 2 USB 2.0 ports that I am connecting to the connecter with.
Cable:
Amazon: USB MIDI Input Output Cable Converter PC Notebook
Works fine on computer and no issues so far via usb.
Thanks!

Any Ideas?

Can anyone help me?
Hi, I have a solution for You.
Download Grand Piano Pro from google play store works perfectly.
Download Floating Browser if You want to do something on top of the app.
I'm using worlde panda 61 midi keyboard via usb on my Transformer Prime
Yep AFAIK, Grand Piano and the Organ app from the same developer are the only 2 apps that supports USB Midi at the moment.
I made a quick video to show it working here
http://www.youtube.com/watch?v=-GygpDwYMVk
There is also USB Midi Monitor, but that is just a utility rather than an instrument or recorder.
I am really keen for more apps to come out so we can record using a USB midi controller.
Does anyone know any more apps that support USB Midi devices?
thanks,
Rich
I presume this should also work if I'm connecting my keyboard via a MIDI to USB converter then to the phone?
Thanks

If it's a standard MIDI device (ie. if you can plug it into a Windows or Mac machine and it shows up as a midi controller without needing to install any special drivers) then it should work.
Excellent thanks. I've purchased the otg cable, I'll report back.
Thanks.

Hi!
My cable arrived and I had a go at connecting up my midi keyboard. After some time I realised that the phone appeared not to be putting enough power through to the midi-usb converter that I use on my PC usually (plug and play), such that the led indicator was not lighting. I bought Grand Piano and Midi Monitor, both showed no response. When I open Midi Monitor there is a pop up that says, no MIDI device detected.
Any help is appreciated!
Thanks,
You could try putting a powered USB hub in between the midi-usb converter and the OTG cable.
That kind of takes away the portability aspect though as you'll be tied to a power point.
But if you have one available, you could at least confirm if that is the issue.
If that does solve the issue, you could try to power the USB hub with a portable power pack... but I'm not sure i that would work...
Thank you thank you for the app listing, Gpp works for midi detection, and is pretty much what I was looking for. It didn't need any power on my tf101. I'll be sure to hit that thanks button at midnight x)
I have a TF300T and a Yamaha keyboard that I connect to my computer via USB (no drivers needed).
I don't have the keyboard for the tablet so I was thinking about buying the USB OTG adapter and connect the piano directly. Is this possible? Anyone has the USB OTG adapter and tried this?
Thanks.

Hi there,
I've got really strange problem with my XPERIA MINI PRO - when I plug in the headphones, the phone wouldn't recognize them.
Only if I've had them plugged before BOOT of my phone.
So, when Iam turning on / rebooting my phone with plugged phones, they're working and recognized, but when I disconnect them, same problem -> phone ignores it.
So, my xperia mini pro can't recognize the action of plugging in phones in general. Have tried official kernel, custom kernel, few roms and its deffinitely a hardware problem.
Does anyone knows how does this phone recognize that? And what might be my problem?
Thanx for any ideas.

i have a similar problem on mine, but mine thinks it has headphones plugged it all the time! i downloaded an app called "headset toggle" it gives you a widget on your home screen to show if headphones are connected or not, and clicking on the icon forces a connect or disconnect of them regardless of wether they are connected or not, should fix your problem:

edit: just to add i have 4.0.4 and it works perfect on my phone
Headset not recognising
i am facing the similar problem...... my headset is also not detecting when i plug in, detecting only when i reset my phone and when i unplug again it's not detecting. i face this problem since i update my mobile to latest version (ICS 4.0.4)

Hello,
I had the exact same problem. It was a hardware problem. The only way is to take it in for service as I did. was repaired at electronics level.
Is it possible to solve this problem with headphones? Any app? Toggleheadset does not work for me. Thanks

did you use a SE headphone or a normal headphone?
i got similar problem. If jack isnt plugged in, there are some electronical noises in microphone, so i cant use, if i remove jack, the phone doesnt recognize. i ToggleHeadset, now microphone works good, and recognized that i removed the jack
what hardware causes this problem? i ask it because i bring my mini pro friday to the service, and maybe i'll ask about it there for repair.

This is a halfway software solution to make the phone work, for a complete repair i believe taking the phone to service is necessary.
I have a hardware problem where xperia mini pro (Stock Rom ICS 4.0.4) is constantly detecting headphones connecting and disconnecting. This stops all the multimedia with sound, so it was impossible to start a music file or video because it was automaticly paused).
Disabling the Live ware app (connect now app) did not help,
This may not work for people who can not make phone play music or videos after headphones are inserted,
I managed to solve problem with software and by inserting headphones in the jack once every boot.
You need 2 apps; soundabout and toggleheadset2 (widget),
soundabout does not need to be registered), you will just need to set soundabout service to run on every boot, and set the 'media audio' output to speaker by default.
Every time phone is booted or rebooted insert the headphones, then play a song, remove the headphones and toggle headset to off, every time you wish to use the headphones you will need to toggle the headset widget to on manually,
i recommend to have phone calls and messages also set to vibrate in case you forget to toggle after unplugging the headphones.
I have not yet managed to get working the headset microphone,
If the headphones work in iPhone they wont work in Xperia mini pro or arcs or 2011 device , u need JVC gummy plus , they come with adaptor to sort the problem

There is 2 headphone and Mic standards omtp and cita and only one headphone standard, older Xperia used a differnt standard to what they use today , everyone jumped on the iPhone standard

Hello so basically while using a Bluetooth mouse on android (not using the phone as a mouse) but connecting a Bluetooth mouse to my phone, it does not register "clicks" well it does but it doesn't basically it will work selecting apps and everything but once in a app the "click" no longer registers.
I've turned on "show touches" and when I click I notice that a "click" isn't there at all although when enabling "pointer location" from developer options when clicking it responds so it knows the mouses exact location ect but does not physically "click/touch"
My question is can anybody help solve this?? Would be really thankful.
Also if you ask why I need a mouse pointer on my phone I don't but what I want it for is my TV, I have a new Sony 4K TV with android as its software, and I have gotten some apps on it I would like to use and they boot up fine issue is after connecting mouse to TV I cannot select anything once inside an app, I've been using my phone to try and figure it out as once I've done it on here can simply recreate that on my TV as is the same platform. Anyway any help would be highly appreciated.
Regards, Bradley.
