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. -- uname -rsvp Linux 3.10.0-1160.49.1.el7.x86_64 #1 SMP Tue Nov 30 15:51:32 UTC 2021 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
