Camera model
Generic 1080p Webcam
lsusb says "Bus 001 Device 005: ID 05a3:9331 ARC International Camera"
What is the problem?
The camera disconnects irregularly. I have no idea why it could be.
What did you already try to solve it?
Recently, I have been monitoring the connection of the webcam. Unfortunately, the data does not yet give me any information about the cause.
Since I started monitoring, the webcam has been running at the following times:
- 2022-03-27 17:12:55 - 2022-03-30 18:40:39
- 2022-03-30 19:00:30 - 2022-04-01 03:15:39
- 2022-04-01 09:27:30 - 2022-04-01 09:54:39
In these times, I mainly printed or the Pi didn't do anything.
After a restart, the webcam was accessible again.
With the last entry, I stopped a print before the connection was lost.
Since I sometimes also had problems uploading data, I looked to see if the CPU or RAM were causing problems during these times, but these values are all in the normal range at the same time.

- It seems that you don't have VL805 (Raspberry Pi 4).
There should be no problems with USB (a.k.a. select() timeout)
