URGENT - usb 1.1 vs 2.0 problems

Hi,

I am running Windows XP under parallels 4.0 on a late 2008 macbook. When i plug in a usb 2.0 device, the device only connects as a usb 1.1 device, instead of a 2.0 device, and i get a bubble saying "this device could perform faster if it were plugged into a hi-speed usb port" in XP. The ports on my computer are usb 2.0 ports. Why isn't parallels connecting the devices to the usb 2.0 ports? I really need the usb device to be recognized as a 2.0 device, because it is a data acquisition device, and the sampling rate needs to function at 2.0 speeds. Does anyone have any ideas? It is kind of urgent, because I need to have this working by early next week.

Thanks in advance
-Evan

2. Click the Hardware tab.
3. Click the Device Manager button.
4. Expand Universal Serial Bus controllers.
5. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove
them one at a time.
