Hello again.

The output is at the bottom of the message.  The offending device is
listed as the "Logitech USB Receiver."

Another thing I just noticed is that the first physical device, which is
standard keys (numbers, letters, etc), is claiming to have keys and
buttons that it does not (or evtest is anyways).

In any case, I'm game to fix this, so I guess I'm looking for
recommendations on where to go from here.  Oh, and sorry for all of the
extra junk included in the dmesg output:
