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).

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?
perhaps the 2nd camera is on the pci bus or an i2c bus?
lspci tells the former, i don't know how to determine the latter.
does dmesg show anything suspicious?
it seems a little odd to me to use the same sensor for cameras pointing
in different directions, wouldn't it take some mirrors or something?
vga resolution cameras are probably dirt cheap. just guessing though...
can you take it apart far enough to see if it looks like one or two
cameras?
maybe one of the android phone forums would have an idea since they
presumably handle phones with similar setups?
