- Where did you get the camera module(s)?
Amazon
- Model number of the product(s)?
B0292
- What hardware/platform were you working on?
Ubuntu Linux 18.04 on a System 76 Laptop
- Instructions you have followed. (link/manual/etc.)
I’m using Cheese, following the instructions at this link Webcam - Community Help Wiki
- Problems you were having?
The camera works as expected when I plug it in. After some time, it stops working: it’s still listed with lsusb
, but Cheese only returns a black screen, and I can’t select other cameras on the laptop, such as the internal camera. Unplugging and replugging the camera temporarily solves the issue.

after the webcam stops working, a bunch of these messages appear in dmesg:
