I have a logitech webcam C170, it's connection uses a USB. It is also located in "Other devices" in the device manager. I downloaded a software for the webcam, but the drivers are unknown, also I know very little about these type of problems. The software (skype, logitech webcam software) is not detecting the webcam. I don't know why it isn't working, and the usb port works fine with other devices. Thanks.
