Hmm. Once I dropped all the debug logging, setting the priority actually seems to solve the problem quite well. I've dropped the queue back down to 30, rebooted a few times, done several tests. I'll do more tests, but this seems to make a big difference. In fact, if I take that code back it out, it fails reliably, and if I put it back in, it succeeds reliably. So I think we have a winner! Now to see if hidapi will accept such a crazy patch. :) -- Phil Dibowitz p...@ipom.com Open Source software and tech docs Insanity Palace of Metallica http://www.phildev.net/ http://www.ipom.com/ "Be who you are and say what you feel, because those who mind don't matter and those who matter don't mind." - Dr. Seuss
