Hey, did you ever find a solution for this problem?
Because I'm having the exact same trouble, I pushed the usb library and the permission file, but the demokit cant find the lib.

mAccessory is null has to do with the Java code of the DemoKit app. I'm sure you've done a mistake modifying the original code to run in Android 3.1 or newer. Won have you written this
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
instead of this:
mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
?
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
instead of this:
mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
?
