I am trying to port android 2.3 to my tablet which is currently running on 2.2.
mine is a freescale imx515 tablet.
otg gadget is working well as I can get adb to work but it does not seem to detect the mouse that I have attached.
The same otg host cable and the mouse is working on the original stock 2.2 rom.
btw, I had to not compile the usb runtime power management in order to get the r10.1 source to boot up android UI.
