Sorry to bump, but I haven't gotten any reply. Is there anyone who has any experience with a dual/camera setup... forward + rear facing (similar to a smartphone).
>From reading the manpage on lsusb, it appears that all usb devices are listed: even those that don't have drivers. Because there is no second device listed in lsusb, I suspect that 10f1:1a26 is in fact *both* the forward facing and rear facing camera. This suggests to me there must be a way to tell the device *which* physical camera to use for input. Alternatively, perhaps the single device "publishes" two separate streams. Perhaps this is not part of UVC. Is there anything in the UVC spec that provides an interface for switching between two inputs/streams on the same USB device? Is there anything in the linux UVC driver that allows for this?
