if I claim the interface with usb_driver_claim_interface, will usbfs respect it? There are only a handful of userspace drivers for this device out there.. and I'm pretty sure they're not active during the test. > For the least ambiguity in your results, run your tests in single-user > mode and without X. It wouldn't hurt to unmount /proc/bus/usb as well. I'll certainly unmount usbfs.. that will be one less possibility. Would X and/or multi-user mode make that much of a difference? X certainly makes it easy to keep system resources busy.
