This item lets you enable or disable the USB function in
chipset. The mainboard acts as USB host, and you can plug
USB devices on the USB connector of back panel. You need
USB driver to support USB devices, normally, they are
provided by USB device vendors or operating system such
as Win95.
Important: The USB function shares INTD with
PCI slot 4. Therefore, if you enable the USB
function, only PCI cards that do not require IRQ,
such as VGA, can be installed in slot 4. The
PnP BIOS assigns an IRQ to VGA only if the
VGA requests for it.

USB legacy keyboard at the same time.
Disable "USB Legacy Support" if you have
USB driver in the operating system.
