I assume that you use ifconfig ng0 10.0.0.2 10.0.0.1 on the remote host.

In the file /usr/src/sys/dev/usb/udbp.c:
Add "#define USB_DEBUG" at the beginning.
In the function udbp_setup_out_transfer()
change:
(void) usbd_setup_xfer( sc->sc_bulkout_xfer,
sc->sc_bulkout_pipe,
priv,
sc->sc_bulkout_buffer,
pktlen,
USBD_SHORT_XFER_OK,
UDBP_TIMEOUT,
udbp_out_transfer_cb);
into:
(void) usbd_setup_xfer( sc->sc_bulkout_xfer,
sc->sc_bulkout_pipe,
priv,
sc->sc_bulkout_buffer,
pktlen,
USBD_SHORT_XFER_OK|USBD_FORCE_SHORT_XFER,
UDBP_TIMEOUT,
udbp_out_transfer_cb);
Then "cd /usr/src/sys/modules/udbp" and "make clean" and "make all install clean"
Unplug your device. Reload the udbp module or reboot the computer.
Run "sysctl hw.usb.udbp.debug=15", plug your device and try again.
