Atheros driver for usb network adapters?

[Torfinn Ingolfsen]

I got myself a SMC network adapter, model SMCWUSBT-G2.
Info from usbdevs:

tingo at kg-i82$ usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel
(0x0000), rev 1.00 port 1 addr 2: full speed, power 500 mA, config 1,
