MCS7730/7830/7832 10/100 USB Ethernet device
mos* at uhub?
driver provides support for USB Ethernet
adapters based on the MosChip MCS7730, MCS7830 and MCS7832 USB 2.0 chipsets,
including the following:
- Delock 61147
- Sitecom LN-030
- Syba SY-U2LAN
All adapters operate with either USB 1.x or USB 2.0 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
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.
driver supports the following media types:
- 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
- Set 10Mbps operation.
- Set 100Mbps (Fast Ethernet) operation.
driver supports the following media
- Force full-duplex operation.
- Force half-duplex operation.
