Swift 3 SF314-56G HD Webcam occasionally works, Device descriptor request failed

My webcam stopped working around 6 months ago. The webcam is unrecognized in Device Manager and shows as Unknown USB Device (Device Descriptor Failed). I tried uninstalling the Unknown USB device, but rarely successful. I also tried reinstalling the Chipset driver and it works occasionally. I have tried booting into Linux and using lsusb, the camera shows up sometime.

    I agree with colleague billsey. However, I would check if resetting the battery solves the problem:

    It sounds as if the camera is faulty. They are fairly inexpensive to replace, I assume if it's been that long that you are no longer in warranty?

    Already did that. I also tested using Ubuntu and its the same, so i think Windows is not the issue.

    Try uninstalling and deleting the driver in the device manager.
