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.
The USB channels support USB 2.0. 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.
Every USB interface provides up to 500 mA current and is 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
ICH9R (MAC) accompanied by the 82579L (PHY, LAN1) and, if present, the 82574L (MAC/PHY, LAN2).
