+.Nm mos
+.Nd MosChip MCS7730/7830/7832 10/100 USB Ethernet device
+.Sh SYNOPSIS
+.Cd "mos* at uhub?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for USB Ethernet adapters based on the MosChip
+MCS7730, MCS7830 and MCS7832 USB 2.0 chipsets, including the
+following:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It Delock 61147
+.It Sitecom LN-030
+.It Syba SY-U2LAN
+.El
+.Pp
+All adapters operate with either USB 1.x, 2.0, or 3.x controllers,
+though performance with 1.x controllers is limited since
+the USB 1.x standard specifies a maximum transfer speed of 12Mbps.
+Users with USB 1.x controllers should therefore not expect to actually
+achieve 100Mbps speeds with these devices.
+.Pp
+A 64-bit multicast hash table is supported,
+single perfect filter entry for the station address,
+all-multicast mode, and promiscuous mode.
+Packets are
+received and transmitted over separate USB bulk transfer endpoints.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width "autoselect"
+.It autoselect
+Enable autoselection of the media type and options (this is the default).
+The user can manually override the autoselected mode by adding media
+options to the appropriate
+.Xr ifconfig.if 5
+file.
+.It 10baseT
+Set 10Mbps operation.
+.It 100baseTX
+Set 100Mbps (Fast Ethernet) operation.
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Bl -tag -width "full-duplex"
+.It full-duplex
+Force full-duplex operation.
+.It half-duplex
+Force half-duplex operation.
+.El
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .

+.Xr usbnet 4
