Sure, will give that a try.

Something like this is the likely cause.

The device is operational. I downloaded music to it from Win2k (a
different machine) and no problems.
Interestingly, after putting music into it on the win2k machine, I
pulled the music out on the linux box -- the song was fine.
So the data gets corrupted when going in using linux, but not coming
out.
And again, this _only_ happens when in X. When I exit X, music
downloaded into the unit plays perfectly.

Neither I am afraid. How much is a bus analyzer? I have a Casio camera
that I need to try and add support for too, so that could come in
handy.
