This line makes me suspicious... I wonder if you are having a hardware
problem. I doubt if there is any EMI (ElectroMagnetic Interference)
strong enough to cause these problems though.

This looks normal so far. This is just what happens when xawtv starts
capturing.

<SNIP>
This is an error that I have not seen before. I have seen similar errors
when unplugging the camera during capture but they only happen once or
twice and then stop. The randomness of the packet lengths makes me
suspect that there is a hardware problem somewhere, such as a pin that
is not making good contact. I don't know enough about USB's failure
modes to say for sure though.
It could also be an issue with the backport. Others have reported 2.2.14
works, though. I have not tried 2.2.15, but I will test it myself
tonight. You might want to try 2.3.99-pre6 instead, as that version
works well here.
