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
     Computer Access Technology Corporation's USB-EL1210A chipset, including
     the CATC Netmate and Netmate II, the Belkin F5U011/F5U111, and the Smart‐
     Bridges SmartLink.

     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 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
     transmit command was issued, however the device failed to acknowledge the
     transmission 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)

HISTORY
     The cue device driver first appeared in FreeBSD 4.0.

AUTHORS
     The cue driver was written by Bill Paul ⟨wpaul@ee.columbia.edu⟩.
