So I don't have QCameraInfo cause I use Qt 5.1.
But QCamera::availableDevices() gives me the same information, I think.
It returns the following:
@device:pnp:\?\usb#vid_eb1a&pid_2821&mi_00#6&18118bcd&0&0000#{65e8773d-8f56-11d0-a3b9-00a0c9223196}{54353d15-e717-4d94-b574-685ce1a209e9}
As the device description it returns:
USB 2821 Device
