Red means there is no data on input 0 With only a display device (lcd) plugged into output0, you should see: x c 0 0 = red x c 1 0 = orange x c p 0 = test pattern I tried to make a quick demo of how to use the UVC over usb, and that failed for me. I have not had time to debug. if you do: x c p e you should get the test pattern on /dev/video0 (or whatever your linux system assigns it) Are you able to see the test pattern on some app that will read from a uvc viddo device? This has worked in the past: gst-launch-1.0 \ -v \ v4l2src device=/dev/video0 !\ decodebin !\ queue ! videoconvert !\ fpsdisplaysink sync=false This gives me a black stream. I need to revert my firmware to Jun 2 2019 v0.0.4-487-g5940dcb or Sep 30 2018 v0.0.4-340-g3fb4e7c as I know one of those had working uvc. but no time today :( > x c 0 0 or other changes give nothing else. > Secondary mde change nothing...
