Issue was solved for android-x86 Gingerbread here, 
http://code.google.com/p/android-x86/issues/detail?id=474 it may 
give a head start for fix, author spoofs unused device id and loads
a secondary driver, but why not fix the original?

I did apply the patch here, http://pastebin.com/Db3TqWUy bad for rowboat but it 
didn't solve the issue and mad things go all over the place.

If it helps anyone here is dmesg and lsusb:
