You could have used USB_DEVICE_AND_INTERFACE_INFO() matching on all
ff/ff/ff to avoid blacklisting the adb interface, but IMHO the patch is
fine as it is.

This being an Android device raises another question though: Are these
interface numbers static?  I assume you can e.g. disable adb?  What
happens to the descriptors then?  Does the device change pid, or are the
interfaces renumbered?
