USB controller or Ports conflict on DELL Inspiron 5547 webcam

My webcam does not work, and it only shows a black screen. in addition, it does not display on the device manager -> imaging devices, but sometimes it does.

Trying to fix this problem, I have diagnosed my device using the pre-boot tool, the PSA diagnostic, and USB controller error occurs(see attachment below).

USB controller error suggests that I should  do this steps to solve the error, but my webcam problem is still there:

  • Please update BIOS.
  • Turn off the computer and reseat the USB device.
  • Try a different working USB device and check if the error is still seen.
  • Restart your computer and rerun the PSA diagnostics.

Although The PSA diagnostics does not detect the **USB controller error** anymore, my webcam is still showing the black screen.
