NAME
     cue -- CATC USB-EL1201A USB Ethernet driver

SYNOPSIS
     cue* at uhub?

HARDWARE
     The cue driver supports the following adapters:

           Belkin F5U111
           CATC Netmate
           CATC Netmate II

DESCRIPTION
     The cue driver provides support for USB Ethernet adapters based on the
     Computer Access Technology Corporation's USB-EL1202A chipset.

     The USB-EL1202A 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.

HISTORY
