How to use WinUSB driver on Windows 8 and above systems for cameras with old firmware that do not support WinUSB

1. Uninstall the original proprietary protocol (if multiple versions exist, uninstall multiple times to completely remove the original proprietary protocol until the camera cannot be recognized in Device Manager and shows yellow exclamation mark)

2. Find the unrecognized camera in Device Manager

3. Right-click to update driver

4. Select Universal Serial Bus devices

5. Click 'Yes' when warning appears, forcing use of WinUSB driver

6. Finally the camera is recognized as WinUSB device in Device Manager

Note: If you plug in a new camera that supports WinUSB or use the old ToupCam driver, the above method may fail.
