Public bug reported:
This issue seems to have been introduced in 5.13 somewhere, I only had
5.13.0-30 and 5.13.0-28 available in grub on the 5.13 branch to test
against, but in both instances all capture devices are labelled as
"Video Capture 3" where previously it would show the device's actual
name. I do still have 5.8 branch and 5.4 branch, and when testing
against 5.8.0-63 it showed the names correctly everywhere, and likewise
with 5.4.0-64.
The number at the end seems to be the number of devices, even though it
is getting the counted digit and repeating it for all of them.
If I run:
$ v4l2-ctl --list-devices
I get:
Video Capture 3 (usb-0000:08:00.3-3):
/dev/video2
/dev/video3
/dev/media1
Video Capture 3 (usb-0000:08:00.3-4):
/dev/video4
/dev/video5
/dev/media2
Video Capture 3 (usb-0000:08:00.4-1):
/dev/video0
/dev/video1
/dev/media0
The devices I have (from lsusb) are:
Bus 003 Device 004: ID 534d:2109 MACROSILICON
Bus 003 Device 003: ID 298f:1996 MACROSILICON ShadowCast
Bus 005 Device 002: ID 0458:6006 KYE Systems Corp. (Mouse Systems) AUKEY
PC-LM1E Camera
Previously the devices would be labelled as:
MACROSILICON
MACROSILICON ShadowCast
AUKEY PC-LM1E Camera
There appears to be a mismatch in the usb bus numbers too. You'll notice
in v4l2-ctl 2 of them are correctly identified as Bus 003 and Device 003
andd 004 respectively (outlined as 00.3-3 and 00.3-4), however the last
device shows 00.4-1 but in lsusb this is received as Bus 005 Device 002
- so it should be 00.5-2 if I'm right in the naming conventions that
should be used.
-----
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
-> About Ubuntu
$ lsb_release -rd
Description: Ubuntu 20.04.4 LTS
Release: 20.04
2) The version of the package you are using, via 'apt-cache policy
pkgname' or by checking in Software Center
$ apt-cache policy linux-image-5.13.0-30-generic
linux-image-5.13.0-30-generic:
Installed: 5.13.0-30.33~20.04.1
Candidate: 5.13.0-30.33~20.04.1
Version table:
*** 5.13.0-30.33~20.04.1 500

3) What you expected to happen
The labels of the USB devices to show up correctly in Zoom, OBS,
Microsoft Teams, Skype, Cheese, etc so that I can identify which device
to use.
4) What happened instead
The labels are wrong and given a generic "Video Camera 3" label for all
of them - where 3 is the number of devices I have connected.
