4.2.2 USB
USB channels 1 and 2 are provided via two standard USB connectors.
USB channel 1 supports USB 2.0 and provides up to 500 mA current.
USB channel 2 supports USB 3.0. Contrary to the USB3.0 specification, channel 2 only provides
500mA current. For higher power requirements, you must use devices with an integrated power
supply.
Both interfaces, USB 2.0 and USB 3.0, are protected by an electronically resettable fuse.
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.
Both Standard USB ports are protected by a combined overcurrent
detection. In case of an overcurrent, even at one port, the overcurrent
protection will turn off both USB ports.
