► BIOS EHCI Hand-Off

Windows XP supports a number of features in the Enhanced Host Controller Interface (EHCI)

specication, 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 is a workaround for OS without EHCI hand-Off support .

The EHCI ownership change should claim by EHCI driver.
