USB NIC udav driver

[Pete C]

I have a cheapo USB NIC,  found in dmesg..

ugen0: <DM9601 USB NIC DM9601 USB NIC, class 0/0, rev 1.10/1.01, addr 2> 
on uhub1

I have complied a kernel including ..

device uhci
device ohci
device usb
device miibus
device udav

per the udav(4) man page .. but ifconfig shows only the onboard  nic ..

am I missing something .. or is this USB NIC unsupported ..


TIA
