6.6 Front panel: USB 3.0 A-D (X106 - X109)
The CB6464 provides four USB 3.0 ports, which are implemented as combination connectors with 4
connectors.
The USB channels support the USB 3.0 specification. All necessary settings for USB can be made in the
BIOS. 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.
The individual USB interfaces can supply a current of up to 900 mA and are electronically protected.
Switch-off of the USB ports by overcurrent protection
USB ports A and B and USB ports C and D are each protected by a common overcurrent detection.
In the event of overcurrent occurring on one of the ports, therefore, both commonly protected USB
ports will be switched off.
