Code 43 Unknown Device for USB connected Logitech C920 webcam
I have been using a logitech C920 webcam for months on this laptop. Yesterday, I plugged it in and got an unknown device message. I reloaded the logitech software from their site. No change. I plugged the webcam into another laptop and it was recognized. I have tried a basic "clearing" of the system by powering down, unplugging the power and removing the battery then holding the "power on" button for 2 min.
Still getting a unknown device no matter which usb port I plug the webcam into.
Any suggestions?
