Use the removable attribute exposed by the USB device in sysfs to infer if the camera is an external (when removable) or front (when non-removable) camera. This is likely not perfect as the removable attribute is derived from ACPI data which may not always be accurate, and non-ACPI platforms likely report all devices as removable. Still, this is a first step upon which a better method could be built.
