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.
