Subject: Allow USB IDs to be non-unique.

When retrieving USB IDs create a list of players matching to a USB ID instead
of assuming only one player.  This prevents non-unique IDs overwriting each
other and will be used for improved autodetection later.

Currently only the first ID is used during detection, and no additional IDs
have been added yet.
