In order to fix the problems, I recommend you access the official web page, select your operating platform and download and install the latest drivers available. If you still have problems, press Windows + R key combination, type devmgmt.msc and click OK. Expand the Universal Serial Bus controllers list, right-click on the driver and select Uninstall. Reboot the PC, connect the webcam using the USB cable, press Scan for hardware changes icon from Device Manager and reinstall the drivers. If it doesn't help, try updating the Windows Installer through Windows Update and run the Fix It utility provided by Microsoft. If the issues persist, contact the support team using the Logitech Support page.
