Comment (by jcardona):

 I've prepared a debug build that captures the suspend/resume execution
 trace and adds it to the debug beacons.  Details here:

 https://cozybit1.dnsalias.org/~javier/logs/suspend_resume_debug_beacon.txt

 With that build cjb was able to reproduce the crash, and on the failed
 machine we see that the USB events were processed out of order.  In
 particular, we see a usb port reset processed before usb resume.  On
 suspend endpoint 0 is disabled and on reset it's re-enabled.  If those two
 events get reversed, we would see a failure on endpoint 0 on the next
 transaction (which, after a reset, is Get Description).
