  Modified files:
    sys/dev/usb          ehci.c 
  Log:
  Let the EHCI hardware track the toggle state for bulk and interrupt
  transfers. This fixes some cases where the software toggle tracking
  was not doing the right thing. For example, a short transfer that
  transferred 0 bytes of the requested qTD transfer size does cause
  a toggle change, but the existing code was assuming it didn't.
