USB support for android emulator

[sugnan prabhu]

Hello People,

     

          I have written few usb drivers for android which works fine on the android-x86 (tested using virtualbox), now i want to test the same for android-arm using android emulator. I have built the android for arm including my usb drivers, but there is no support for the usb connectivity on android emulator, so can some one give some pointer how can i add the usb support for it. If any one with the knowledge on this stuff, please suggest.

         

          I thought of using qemu directly instead of emulator, but misses lot of android hardware support, i want to contribute this for the android opensource, some one give me some pointers.

While noble, that sounds like an ambitious project at a time when most
arm distributions of android aren't AFAIK shipping with an enabled USB
host mode, or a way for users to gain permission to load kernel
modules.

To really test your drivers it may be necessary to find hardware or
make massive modifications to the emulator. But just making sure your
code will compile, and having it well documented (along with any
quirks of the USB peripheral) would put someone in a position to try
building the driver for their arm-based android device in a good
position.

I should clarify that by "most arm distributions" I mean most by
installed base - ie, the locked-down consumer oriented ones.

Probably if your time is worth anything and you want to do this, you
would be better off with a beagle board than trying to adapt the
emulator to proxy your pc's USB ports so you can test drivers against
hardware.
