kue -- Kawasaki LSI KL5KUSB101B USB Ethernet device
kue* at uhub?
The kue driver provides support for USB Ethernet adapters based on the
Kawasaki LSI KL5KLUSB101B chipset. This includes the following adapters:
3Com 3c460 HomeConnect
AboCom Systems URE450 Ethernet
ADS Technologies USB-10BT
Asante USB to Ethernet
I/O Data USB-ET/T
Jaton USB XpressNet
Portsmith Express Ethernet
Psion Dacom Gold Port Ethernet
Shark Pocket Adapter
The KL5KLUSB101B supports a 128-entry multicast filter, single perfect
filter entry for the station address and promiscuous mode. Packets are
received and transmitted over separate USB bulk transfer endpoints.
The Kawasaki 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).
The driver needs a firmware file, which is loaded on demand when the
device is attached:
kue0: watchdog timeout A packet was queued for transmission and a trans-
mit command was issued, however the device failed to acknowledge the
transmission before a timeout expired.
kue0: no memory for rx list The driver failed to allocate an mbuf for
the receiver ring.

The kue device driver first appeared in FreeBSD 4.0. OpenBSD support was
added in OpenBSD 2.7.
The kue driver was written by Bill Paul <email@example.com> and
ported to OpenBSD by Aaron Campbell <firstname.lastname@example.org>.
The kue driver does not accumulate Ethernet collisions statistics because
the Kawasaki firmware does not appear to maintain any internal statis-
