keyboard or mouse, set to auto or enabled.

This item is used to set the transmission rate mode of USB 2.0. The available settings are :

► BIOS EHCI Hand-Off
Windows XP supports a number of features in the Enhanced Host Controller Interface (EHCI)
specification, but there are a few features that are not implemented. Microsoft said preliminary
support for EHCI BIOS handoff will be available in Windows XP SP2.
This item allows you to enable support for OS without EHCI hand-off feature.
This is a workaround for OS without EHCI hand-Off support .
The EHCI ownership change should claim by EHCI driver.
