CB7268 16 Version: 1.1
5.6 Front panel: USB 3.1 GEN2 (X106-X109)
The USB channels 1, 2, 3 and 4 are made available via a standard USB connector.
These USB channels support the 3.1-GEN2 USB specification. In contrast to the specification, the USB 3.1
channels only supply current up to 500 mA. Devices with their own current supply must be used for higher
power demands. The USB interfaces are electronically protected.
All necessary settings for USB can be made in the BIOS. This applies to the USB interfaces. Note that the
"USB mouse and keyboard" function in the BIOS setup is only required if the operating system does not offer
USB support. This function should not be selected for settings in the setup and for booting Windows with a
USB mouse and keyboard connected, because this would lead to considerable performance limitations.
