Under My Computer, Device Hardware, select USB hubs, and click UPDATE
DRIVER; automatic find and you should be good to go. WinXP did not
automatically support USB2.0, only 1.1; WinXPsp1 did, but only switched to
USB2.0 if you manually told the machine to upgrade the drivers.
If that is not the problem; see if Belkin has a patch/update/driver.
