USB Configuration
Legacy USB Support
Legacy USB Support refers to USB mouse and keyboard sup-
port. Normally if this option is not enabled, any attached USB
mouse or keyboard will not become available until a USB com-
patible operating system is fully booted with all USB drivers
loaded. When this option is enabled, any attached USB device
(such as mouse or keyboard) can function even when there is
no USB driver loaded on the system (e.g. during boot and while
using DOS). Set this value to enable or disable the Legacy
USB Support.
EHCI Hand-off
This is a workaround for OSes without EHCI hand-off support.
The EHCI ownership change should be claimed by the EHCI
driver. Options: Enable, Disable.
USB transfer time-out
This item sets the time-out value for Control, Bulk and Interrupt
transfers. Options: 1 sec, 5 sec, 10 sec, 20 sec.
