    From the EHCI specification of Intel, it said that UHCI is also
    supported through "Companion Controller". Now, a question is whether
    a old device driver(USB 1.1) written for UHCI can be directly used in
    the computers that supports USB 2.0. If the driver can't work with USB 2.0,
    please give me some advices to make it work.
