### 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.

### SEE ALSO

### HISTORY

The cue device driver first appeared in FreeBSD4.0, and in NetBSD1.5.
