Do you see _anything_ in `/var/log/messages' when you attach the disk to
your FreeBSD system?

When I attach a local MyBook I have with a USB cable, `/var/log/messages'
shows:

kernel: umass0: <Western Digital My Book, class 0/0, rev 2.00/10.28, addr 2> on uhub6
root: Unknown USB device: vendor 0x1058 product 0x1102 bus uhub6
