My Gateway W340UI laptop no longer recognizes the CD drive. It is not listed on the available drives.

Also, all 3 USB port fail to recognize any device plugged into them. My mouse worked until today and I have attempted a new mouse.

Thank you for any help you can provide.

Hello,
This may be caused by a hardware filter that is installed through Windows updates.
Click Start then Run and type regedit...click "Ok"

In the left pane, expand (click +) HKEY_LOCAL_MACHINE, then SYSTEM, then CurrentControlSet, then Control, then Class, and click on {4D36E965-E325-11CE-BFC1-08002BE10318}

Right click on {4D36E965-E325-11CE-BFC1-08002BE10318} and choose Export. Name this file "filters" and save it to your desktop. This file can be deleted when it is determined it is no longer needed.

In the right pane, if either UpperFilters or LowerFilters are present, right click on it and choose Delete...accept the deletion. Delete both if they are both present.

Close Registry Editor and reboot.

Hfcg, is this location the same in both Vista and XP?

Yes, the location is the same in Vista.
I had to do this to my machine after I had updated the Vista installation.

Awesome, I am saving this to my canned speeches because this seems to come up really often.
