[SOLVED] USB webcam: micro works, camera not

larshenric · 02-19-2022, 12:10 PM

After a lot of years with Ubuntu I switched to Elementary OS 6.1. Unfortunately there is a problem with my USB webcam that I use on video conferences. lsusb recognizes it, the microphone works, but not the camera. Is there anybody who can help? :-)

dave67 · 02-20-2022, 07:20 AM

What applications have you tried with the cam?

larshenric · 02-20-2022, 09:08 AM

Thanks for replying! :-)
I used "Camera" (elementary OS app), google's "Hangout", "bigbluebutton" video conference app...
As I wrote: webcam microphone works, camera not...

dave67 · 02-20-2022, 07:34 PM

Google has abandoned Google hangouts

https://tech.co/news/google-hangouts-replaced

Google has suggested using Google meet

This may work or it may not.

I suggest trying meet see if the cam video works.

larshenric · 02-21-2022, 03:57 AM

It was actually "meet" I used, I just named it "hangout"...
So, in "meet" it doesn't work either... :-(
But thanks for your help!

I suggest you try this

Thank you! That might(!) fix google problems, but not the problems with the system camera apps...

From what I remember elementary only has its package manager which is limited. Unless The elementary team installed synaptic by default? You can install synaptic by the command-line. You will need webcam software to access the webcam locally.

Code:

sudo apt install synaptic

Hello dave67! :-)
I appreciate your help, but it seems that up to now I didn't describe my problem as needed. I already have 2 apps installed, "camera", that comes with the installation of elementaryOS, and "webcamoid". Both apps recognize the microphone function of the external webcam, but NOT the video function...

dave67 · 03-01-2022, 04:07 PM

I assume it was working on Ubuntu before you switched to Elementary Os?

What are the results of this command

Code:

ls -ltr /dev/video*

larshenric · 03-03-2022, 09:41 AM

Right: It was working on Ubuntu.
And here is the output:
Unable to access '/dev/video*': File or directory not found

dave67 · 03-04-2022, 09:04 AM

Looks like Ubuntu has a driver that elementary does not.

Might have to install this tool

Code:

sudo apt install hwinfo

Than please type post the output.

Code:

sudo hwinfo --usb

The output is:

It looks to get a kernel bug with this webcam. Not the webcams fault. Please type

Code:

Uname -r

This will show the current kernel being used. I will see how easy jt is to change kernels if need be in elementary. You are using elementary 0S 6 right?

Here is the bug report not a good read though

Yes, it's elementaryOS 6.1. And output: 5.13.0-30-generic
