Hello

motionplus.conf

a basic example of the configuration file for a usb webcam would be a good thing.
yes I can't display an image in the interface.

the webcam is functional

It is done by specifying like this:

v4l2_device /dev/videoX

I'll note to add more specificity to the the example and/or guide.
