Problems with imaging devices after uninstalling Logitech drivers

The problem:
After uninstalling Logitech's QuickCam software and drivers, all imaging devices (cameras, webcams, scanners) no longer work in Windows. In the device manager, a yellow exclamation mark icon is displayed, along with this message: "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"


The solution:
1) Reboot into safe mode (press F8 at startup), navigate to C:\windows\system32\drivers, and rename the file lvmvdrv.sys to lvmvdrv.sys.backup

2) Open the registry editor (Start > Run > regedit > OK) and in the left pane navigate down to My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlS
et\Control\Class\{6BDD1FC6-810F-11D0-BEC7-08002BE2092F}.

3) Right click that key (the folder icon you just navigated to) and select Export. Save this to your desktop for now. If for some reason things don't work out after all is said and done, you can double click this file and undo the rename from step 1, reboot, and you'll be back where you started.

4) With the key you just exported being selected in the left pane, on the right you should see a Multi String Value named LowerFilters, with lvmvdrv as it's data. Right click this MSV and delete it.

5) Reboot. Your imaging devices should be working now.
