Greg:
When you refactored the USB device-matching code, you may have introduced
a bug. Does it seem reasonable that an entry might contain both
device-specific and interface-specific criteria to match? In which case
both sets of matches would have to succeed, not just one.
So is the patch below needed? If yes, I'll send it with a proper patch
comment and S-O-B.
