4.10 USB 1-4
The USB channels 1 to 4 are available as standard USB connectors.
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.
