NAME
     cue -- CATC USB-EL1210A USB Ethernet driver

SYNOPSIS
     device uhci
     device ohci
     device usb
     device cue

DESCRIPTION
     The cue driver provides support for USB ethernet adapters based on the Com-
     puter  Access  Technology	Corporation's USB-EL1210A chipset, including the
     CATC Netmate and Netmate II, and the Belkin F5U011/F5U111.

     The USB-EL1210A supports a 512-bit multicast hash	filter,  single  perfect
     filter entry for the station address and promiscuous mode.  Packets are re-
     ceived and transmitted over separate USB bulk transfer endpoints.

     The  CATC adapter supports only 10mbps half-duplex mode, hence there are no
     ifmedia(4) modes to select.

     For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS
     cue%d: watchdog timeout  A packet was queued for transmission and a  trans-
     mit command was issued, however the device failed to acknowledge the trans-
     mission before a timeout expired.

     cue%d: no memory for rx list  The driver failed to allocate an mbuf for the
     receiver ring.

SEE ALSO
     arp(4), netintro(4), ng_ether(4), ifconfig(8)
