False "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port."

False "This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port."

I have a laptop, Dell Latitude CX840, and this message keeps

occurring. The problem is, these are USB 2.0 ports. I have this

machine dual boot Windows 2000 with USB drivers, and it recognizes and

runs in 2.0 mode, just on the basis of considerably faster copying

times from USB mass storage devices.

All devices connect in 1.1 mode when in XP. I don't think this was a

problem in SP1, occurred after I applied SP2. Are there steps to make

it work in 2.0 mode?

Do you have the motherboard chipset drivers installed for XP?

Device manager should show whether USB devices are connecting to USB1 or

USB2 controllers. UVCVIEW from MS downloads will also show you which USB

device is connecting to which USB port/hub/controller with some extra

details.
