Dell Technologies VEP4600 BIOS User guide

USB 3.0

To support universal serial bus (USB) 3.0 in operating systems, set the extensible host controller interface (xHCI) XHCI Hand-off option to enabled. Access this setting from the BIOS setup screen, select the Advanced tab, then select USB Configuration.

If the BIOS must support USB 2.0 devices—legacy USB devices—leave Legacy USB Support set to enabled, shown below.

Because the box is connected using the universal asynchronous receiver-transmitter (UART) console, traditional keyboard or mouse are not connected to the USB ports.
