    sys/dev/usb          ugen.c 
  Log:
  * When toggling short transfers on a bulk transfer endpoint, cancel and
    restart the current waiting transfer.  If this isn't done, the device's
    next transfer (that we would like to do a short read on) is going to
    return an error -- for short transfer.
  * For bulk transfer endpoints, restore the maximum transfer length each
    time a transfer is done, or the first short transfer will make all the
    rest that size or smaller.
  * Remove impossibilities (malloc(M_WAITOK) == NULL, &var == NULL).
