I've had my fair share of USB fun myself, yeah.

The problem is difficult to track, you are using an old kernel. If
it's possible to use a recent kernel, I'd try that first.

Also, the USB setup: Is the stick connected directly or via hub? What
about scheduler? PREEMPT? I'm just taking a wild guess here.

The USB mailing list at linux-usb@xxxxxxxxxxxxxxx might be a better
place to ask, people there have a deeper knowledge about things that
could cause your problem. Worth a try.
