3.2.6 USB and LAN
To save space USB and LAN connectors are provided in the form of combo connectors. These either
comprise two USB connectors or two USB connectors and one LAN connector. This way all board
variants provide four external USB channels.
USB channels 3 and 4 support USB 2.0, furthermore USB 1 and 2 support USB 3.0. You may note that
the setting of USB keyboard or USB mouse support in the BIOS-setup is only necessary and advisable, if
the OS offers no USB-support. BIOS-setup can be changed with a USB keyboard without enabling USB
keyboard support. Running Windows with these features enabled may lead to significant performance or
functionality limitations.
The 2.0 USB interface provides up to 500 mA current, the 3.0 USB interface provides up to 900mA. All
USB interfaces are protected by an electronically resettable fuse.
The board comes in different variants, some with one Gigabit-LAN connector, others with two. All LAN
connectors support 10/100/1000 Ethernet with automatic bandwith selection. Controller chips are the
LynxPoint (MAC) accompanied by the i218 (PHY, LAN1) and, if present, the i210(MAC/PHY, LAN2).
