HP Pavilion dv7-6c95dx HP TrueVision HD webcam no longer detected.

Hi Ronald,

Unknown USB Device (Device Descriptor Request Failed),  0xA00F4244(0xC00DABED) error can be attributed to these possible causes:

1. Using an outdated version of drivers.
2. Issue with the motherboard of the system.
3. Software or hardware component errors.
4. Unstable or corrupt USB controllers.

To resolve this issue, follow the methods below:

Method 1: Use Hardware and Devices troubleshooter

1. Press Windows key + R button to open the Run box.
   
2. Type in "Control" and hit Enter.
3. On the Control Panel, use the search box and type "troubleshooter" and select "Troubleshooting."
4. Go to troubleshooting Hardware and Sound device.
5. Select "Configure a device" under "Hardware and Sound" and follow the on screen instructions.
6. Fix USB Device Not Recognized. Device Descriptor Request Failed
7. If the problem is found, click on "Apply this fix."

Method 2: Uninstall Drivers

1. Press Windows key + R button to open the Run box.
2. Type in "devmgmt.msc" and hit Enter to open Device Manager.
3. On the Device Manager, expand Universal Serial Bus controllers.
4. Shown is an Unknown USB device (Device Descriptor Request Failed) with the yellow sign in Universal Serial Bus controllers.
5. Right-click on it and click Uninstall to remove them.
6. Restart your laptop and the drivers will be automatically installed.

Let us know if you need anything else.

I tried both methods but they did not help.  In method 1, received the reply: Troubleshooting couldn't identify the problem. In method 2, the error returned with reboot.  Is there anything else I can try?

Does anyone else have something else I can try? I still can't get my laptop to detect my webcam.

Have tried all of the above and still no cure for missing web cam.  I really don't want to reinstall windows 10, again, since everything but to web cam works.
