Let's try a different route of uninstalling the existing driver, then running Windows update, then trying to reconnect the Webcam.
First,
Unplug both of the Lifecams from their USB ports, and leave them unplugged for now.
Next,
- Press “Win + X” and select “Command Prompt (Admin)” from the list of options
- Type the following and press the Enter:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
- Press “Win + X” and select "Device Manager"
- Go to “view” and select the option “show hidden devices” to reveal all the hidden and old drivers.
- Select the driver for the HD LifeCam (the name should include "LifeCam" in it but I'm not sure of the installed driver's exact name for that version), Right-click and select "Uninstall".
- The next step I suggest is to use a "Registry Cleaning" program to remove the former Driver's Data from the registry. Sadly, Microsoft doesn't provide such a tool and I can't post a link to one here, but there are several available via a Google search. This process MIGHT working without running a Registry Cleaner but I feel it would help to improve the chances of success.
- If you've been able to find a Registry cleaning program, run it, if you have not, please restart your computer now.
- Once restarted please update Windows by going to Windows Update and selecting "Check for Updates Now".
You can access Windows Update by selecting "Settings" in the Start Menu (that's the gear icon),. then selecting "Updates and Security", next select "Windows Update" and select "Check for Updates Now".
- If updates are found please install them, and once the updates successfully install please restart your computer.
9B. If no updates are found, then restart your computer at this point, however, it's important to let updates found install even if they seem unrelated to this issue.
- After restarting your computer, now plug in your LifeCams and see if they work normally.
Please let me know if the above process helps.
