** Description changed:
Very recently my HDMI-->USB video capture device stopped working.
/dev/video{0,1} is no longer created so it can no longer be accessed.
The device in question was bought from eBay:

Photo attached, just in case.
linux-image-5.4.0-42-generic works.
linux-image-5.4.0-45-generic fails.
There appears to be no intermediate kernel releases.
