  Modified files:
    sys/dev/usb          uvisor.c 
  Log:
  Crank down UVISORBUFSIZE from 1024 to 64 to avoid a problem where
  the Palm device and the USB host controller deadlock. The USB host
  controller is expecting an early-end-of-transmission packet with 0
  data, and the Palm doesn't send one because it's already communicated
  the amount of data it's going to send in a header (which ucom/uvisor
  are oblivious to). This is the problem that has been known on the
  pilot-link lists as the "[Free]BSD USB problem", but not understood.
