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

After updating my Hp Pavilion dv7-6c95dx from windows 7 64 bit to windows 10 64 bit home, my laptop no longer detects my webcam.  In Device Manager, I'm getting the following errors: Unknown USB Device (Device Descriptor Request Failed),  0xA00F4244(0xC00DABED). I've searched thru the internet and have tried the listed fixes but have had no luck.  Please help

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 Using an outdated version of drivers.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.

To resolve this issue, follow the methods below:

  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.

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?

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.
