For the first time, I have now needed to connect to a USB 2.O port for a SanDisk Cruzer USB Flash Drive. It will work but at 1.O speed. A message appears "Hi speed USB Device attached to non hi-speed hub". I checked my motherboard's handbook and the ports that are being used are for USB 2.0. The motherboard manufacturer states that the drivers in my Service Pack 1 needed to be activated for the USB 2.O. However, using the automatic driver update function thru XP'S Device Manager indicates those installed are the most current.

1. How can I really check what version of USB drivers are really installed and
the steps to do this?
2. What else can be wrong?

Thanks

I wouldn't look to MS to provide USB 2.0 drivers; rather I would get them direct from the M/B manufacturer. Also, consider the possiblity that your M/B doesn't support USB 2.0. This happened to me.

Also (my favorite word), some M/B's have jumpers to enable/disable USB 2.0, as well as BIOS settings that do the same. I'd check BIOS first, to make sure it is enabled. Then verify that the M/B supports it. Then get manufacturer's drivers. Then start looking at the jumpers.

Open the Device Manager, and see what is listed for your USB hardware (Enhanced means 2.0)

If I am reading your post correctly, you only have SP1 installed. Install SP2 and make sure all other updates are installed.
