This also happened to me in 20.04, but only sometimes. After moving to a
new computer and installing 22.04 on that, my DS-U02 wouldn't work at
all. This is what `sudo dmesg` brings up whenever it's plugged in.

The UVC error varies with every reconnect but, this is the most common
one to pop up.

Title:
External USB webcam is not working
Status in linux-signed-hwe-5.13 package in Ubuntu:
Confirmed
Bug description:
Hello, I'm trying to connect Hikvision DS-U02 USB Webcam. It worked
for once after trying multiple times, then it stopped working again.
It worked when I connected it to a USB 2.0 port and now it's not
working there as well. The device is showing up in lsbsb and dmseg,
but not showing in "v4l2-ctl --list-devices".
