lines in your
kernel configuration file:
      device uhci
      device ohci
      device usb
      device cue
Alternatively,  to load the driver as a module at boot time,

DESCRIPTION

The cue driver provides support for USB Ethernet adapters

based on the
Computer Access Technology Corporation's USB-EL1210A

chipset.

The USB-EL1210A supports a 512-bit multicast hash filter,

single perfect
filter entry for the station address and promiscuous mode.

Packets are
received and transmitted over separate USB bulk transfer

endpoints.

The CATC chipset supports only 10Mbps half-duplex mode,

hence there are
no ifmedia(4) modes to select.

For more information on configuring this device, see ifcon

fig(8).
