ms2109 linux (MacroSilicon USB Video)

instructions.md

Play

ffplay -f video4linux2 -framerate 60 -video_size 1920x1080 -input_format mjpeg /dev/video2

You can try other video number (video3, video4)

Maybe you need:

Create: /etc/udev/rules.d/91-hdmi-to-usb-ms2109.rules With:

# For HDMI-to-USB adaptor:
SUBSYSTEM=="usb", DRIVER=="snd-usb-audio", ATTRS{idProduct}=="2109", ATTRS{idVendor}=="534d", \
    RUN+="/bin/sh -c 'echo -n $kernel > /sys/bus/usb/drivers/snd-usb-audio/unbind'"

SUBSYSTEM=="usb", DRIVER=="snd-usb-audio", ATTRS{idProduct}=="2109", ATTRS{idVendor}=="534d", \
    ATTR{bInterfaceNumber}=="00", RUN+="/bin/sh -c 'sleep 1; echo -n $kernel > /sys/bus/usb/drivers/uvcvideo/bind'"

Reload: sudo udevadm control --reload-rules

then unplug and replug, and it should start working.

Appreciate the notes on this. I can't get /dev/video devices to show up in WSL2/Debian Bookworm despite adding the udev rules. I am using usbip to attach the device to debian. It shows up in dmesg and lsusb. If anyone has this working, please share.
