Description
Use this option to enable USB mouse and
USB keyboard support. Normally if this option
is not enabled, attached USB mouse or USB
keyboard is not available until a USB
compatible operating system is fully booted
with all USB drivers loaded. When this option
is enabled, any attached USB mouse or USB
keyboard can control the system even when
there is no USB driver loaded onto the
system.
This item allows you to select HiSpeed
(480Mbps) or FullSpeed (12Mpbs).
This is a workaround for OSs without EHCI
hand-off support. The EHCI ownership
change should be claimed by EHCI driver.
The USB FDD is a slim type floppy disk drive
(FDD) with a Universal Serial Bus (USB)
interface.
