Right.  If I stick my Cruzer into my T30 in XP it says "This device can=20
perform faster..."   The Cruzer then works at the slow speed.   No fault =

the Cruzer, the T30 does'nt have USB 2.0 host controller. =20

But I have another one (might be Memorex) here that will not work in XP o=

T30.    It will work on a machine that has USB 2.0 host controller.

I have also seen USB flash drives not work when connected to a USB 4 port=

hub.
