3.4 Internal Connectors
3.4.1 USB 5-8
The USB channels 5 to 8 are provided via two 2x5 pin connectors (FCI 75869-301LF).
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 an 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 electronical fuse.
