use uvc as primary camera

[MarkHaysHarris777]

Both of the usb ports are usb2.0 and can be used for things like drives, keyboards, and even cameras;  however, only the bottom port can be used OTG (the usb port closest to the board).

Are you sure about that Marcus? It is documented as being the top port.

Thank you!   What is the source of the thumb nail ?   Also, then that means that the FEL port (top) is the same as the OTG hardware port  too (top) ?  I've looked through the SoC user manual, but apparently I missed it;  can you provide a page number?

Note:  I did confirm through reliable sources on-line (irc) that the FEL port (top usb port) is the OTG hardware port (furthest from the board vertically).

If the board is booted without the SD card in place the machine goes into FEL mode , and the pine board (using FEL port) will be visible to the PC as a device-- the pc will be able to write to the pine memory , and read the pine memory (although, not immediately useful, it is a cool academic exercise);  however,  when booted in gnu+linux there isn't a usb OTG controller available , so with linux only two (2) usb2.0 host ports are available;  no OTG port is available.
