the majority of the USB MP device interface is documented in usbdivar.h.


flesh out most of usbdi(9).

usb_event_thread() startup should use something to sync companions

usb_detach_{waitold,wakeup} to usb_detach_{wait,broadcast} conversion:

use usb_delay_ms_locked() in places


convert uhidev users to MPSAFE:
  ucycom(4)
  - own cdevsw that isn't D_MPSAFE; need to check intr handlers

  uhid(4)
  - D_MPSAFE not set as all users need it first.
  - mostly done

  ukbd(4)
  ums(4)
  uts(4)
  pbms(4)
  - depends upon wscons? check intr
