Dmesg output with usb_snoop and usb_snoop_max is attached below.

We've tested this application on a handful of other platforms and have
really only had issues with this desktop and our tablet device which
is stuck on the 2.6 kernel. Looking at the output of that tablet when
it gets "stuck" (this was posted back on the original libusb post)
makes it also seem like it may have some other problem than the one we
have been debugging here. Not sure if we can provide any other input
here that would help in making that decision.
