USB channels 1 to 8 are provided via two 2x8pin connectors (FCI 98424-G52-16LF, mating connector
e.g. FCI 90311-016LF).
All 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 a USB
supporting OS (such as Microsoft® 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.

on the Mini Card connector (if populated, p. 22).
