Unfortunately, this doesn't work. If I plug a USB device with an USB-C adapter to the USB-C port of the laptop, the device still shows up the first controller. I don't know what the second controller does. So the original question remains: Does anyone know a good external webcam that will work with USB forwarding? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
