Thanks Dallas.

The ID says: USB/UNKNOWN

Do you need any more information?

Dbl click on the unknown device, click on the detail tab and select hardware id and copy and past them here.

Ok, from the top downs the values are:

Ok, no problem. Thanks again.

I am going to have to get a second opinion

ok, there are more than 40 values. Which one do you need?

What are the Values

Does the system have a fingerprint reader? Those are usually USB.  So too can memory card readers be USB. 

I asked ejn63 to see what you got. Thanks ejn63 for dropping in.. He might be better apt to help you.

Thanks Dallas for the referral to EJN63.

The pc does not have a fingerprint reader but it does have a memory card reader.

This memory card reader is not in the USB Drivers section in Device Manager, but in the ATA ATAPI IDE Drivers section with 3 lines:

1) Ricoh PCIe Memory Stick Host Controller

2) Ricoh PCIe SF/MMC Host Controller and 

3) Ricoh PCIe xD Picture Card Controller.

I don´t know if it also must be in the USB Drivers section.

EJN63 is your man but while you're waiting...

If everything mentioned works fine then it may be a ghosted driver. If that's the case a few things you could try:

1. When you go to uninstall the unknown driver is there the box that says:

"Delete the driver software for this device" ?? If yes then check the box, uninstall and reboot. Message gone ? If no try 2.

2. Unplug your mouse from usb port. Then, using your touchpad, bring up the Device Manager. Do you still see the unknown driver ? If yes right-click on any text and select "Scan hardware...". Still there run the uninstall  from 1 (with Delete option if available). Close all and restart.


If this doesn't fix it there is an Urgent upgrade for your system software that may be required. (Normally this is the first thing you install after the OS so unsure if you can swap it in now.)

Your operating system is Vista, 32 or 64 ?   

Your mouse is wired (not wireless) ?

btw, your memory card drivers are fine where they are.

How is your Webcam performing? Do you see an entry in Device Manager for the Webcam?
