+.Cd "device uhci"
+.Cd "device ohci"
+.Cd "device usb"

+.Cd "device rue"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB Ethernet adapters based on the RealTek
+RTL8150 USB to Fast Ethernet controller chip.
+This includes the Melco Inc. LUA-KTX and the GREEN HOUSE GH-USB100B.
+.Pp
+The RTL8150 contains a integrated Fast Ethernet MAC, which supports
+both 10 and 100Mbps speeds in either full or half duplex.
+Although designed to interface with
+100Mbps peripheral, the existing USB standard specifies a maximum
+transfer speed of 12Mbps.
+Users should therefore not expect to actually
+achieve 100Mbps speeds with this device.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxx
+.It autoselect
+Enable auto selection of the media type and options.
+The user can manually override
+the auto selected mode by adding media options to the
+.Pa /etc/rc.conf
+file.
+.It 10baseT/UTP
+Set 10Mbps operation.
+The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex
+modes.
+.It 100baseTX
+Set 100Mbps (Fast Ethernet) operation.
+The
+.Ar mediaopt
+option can also be used to select either
+.Ar full-duplex
+or
+.Ar half-duplex
+modes.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Pp
+.Bl -tag -width xxxxxxxxxxxxxxxx
+.It full-duplex
+Force full duplex operation.
+.It half-duplex
+Force half duplex operation.

+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "rue%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.
+.It "rue%d: rx list init failed"
+The driver failed to allocate an mbuf for the transmitter ring.
+.It "rue%d: no memory for rx list"
