Jonathan Ryshpan:
A very good suggestion. I switched the camera with a bluetooth
dongle: the dongle works on both ports but the camera only works on
one. Go figure...
If any motherboard components have aged badly, it may not be able to
supply power well enough on one of the ports. And it's likely your
camera uses more power than the bluetooth dongle. The camera may not
be fully initialising itself.
A quick look at your log files looks like the failing one is trying to
use it as a sound device (which is sensible if it has a microphone
built in), and failing on that half. That could be a system
recognition problem, or still a power problem (if the camera uses
independent chips for sound and vision, it's easy enough that one part
will fail differently than the other).
If I try plugging two USB webcams into my computer (experimenting with
basic webcams and OBS Studio), everything USB-related on my PC goes
haywire. They do have different chipsets, so it shouldn't be a
software clash.
