USB Ethernet Adapter

[nans_nans1 at yahoo.de]

Can someone give me short instructions how to configure a USB Ethernet Adapter on Dfly?
After attaching the adapter a "usbconfig list" said:

ugen0.5: <AX88179 ASIX Elec. Corp.> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (248mA)

A "ifconfig" show only these interfaces (re0 is my regular network interface):

re0: 
faith0: 
lo0: 
ppp0: 
sl0:
