[SOLVED] :Laptop camera is not getting detected LM 20.1 ( no device found error)
Hi all,
today I noticed conferencing tools like zoom, teams etc are not detecting laptop camera. I tried Cheese, restored to the earlier version of back up of 5-6 days but nothing working.
It sometimes works but after sometime again goes back to the same issue.
Same thing happens with Cheese, it shows Camera working with Chesse sometime and stops after that.
This laptop has windows 10 and Linux mint installed.
system details.

Please let me know any more details required for you to help me.
Thank you so much in advance.

Hello dbmatre,
I've looked in the Linux Hardware Database and found, that your laptop seems to have this webcam:
https://linux-hardware.org/?id=usb:0bda-5520
But it isn't detected with the lsusb command. Please post the output of the following command, with which you cam see, if the driver has found the webcam device:
There is another possibility: The webcam is why so ever disabled in your BIOS/System Configuration, although it should be enabled by default. Here is the link to your manual. Go to page 21 and read the description:

Hello dbmatre,
I hoped, that the dmesg command shows something like this (it's my output):
You can see the device ID 046d:0825 for my webcam. I've looked again in the Linux Hardware Database and found another possible webcam for your model:
https://linux-hardware.org/?id=usb:0c45-671e
Both webcams are UVC compatible devices, so they should normally work. In your first post you wrote, that sometimes you got it going, so sometimes it's recognized. I don't know, what to do now, I can only tell, what I would try:
1.) Reset BIOS to default and see, if that helps. If you changed something in BIOS, you could do it again afterwards.
2.) If not, disable Secure Boot in BIOS (although that shouldn't have an effect on it).
3.) For the next boots, always run at first the dmesg command from above to see, if the webcam is recognized. If yes, write down the device ID and try for example guvcview (from the software manager) instead of cheese.
4.) There is a website for Linux UVC Devices with a troubleshooting help. You could run the commands (when you see, your webcam is recognized) and send them the mentioned log files. Maybe they can help.

In between you maybe could use your smartphone connected via USB and it's cam as a workaround. Let me know the results.

Re: Laptop camera is not getting detected LM 20.1 ( no device found error)
I'm wondering if win is getting in the way, have you turned off fast start/boot in win?

Re: Laptop camera is not getting detected LM 20.1 ( no device found error)
Thanks for pointing that out AndyMH, I didn't see the dual boot. That could be the solution.
Re: Laptop camera is not getting detected LM 20.1 ( no device found error)
There is also often one of the F# function buttons along the top of the keyboard that toggles the camera on/off.
Have you checked that? Mine was off by default when I first installed Linux but easily turned on.

Re: Laptop camera is not getting detected LM 20.1 ( no device found error)
I did following and it started working, hopefully it will work seamlessly in future.
I did login to the Windows 10 and disabled fast start/boot inside power setting from control panel.
when I logged into Windows 10 after a long time there were many windows and firmware updates were pending for install. I installed all of them.
so no sure which one did the trick.
Thank you everyone for the time and support

Re: [SOLVED] :Laptop camera is not getting detected LM 20.1 ( no device found error)
Hello dbmatre,
that sounds good . I think, it was the fast startup, because it often causes problems in dual boots on the Linux side. Just out of interest: which webcam is installed in your laptop? Maybe you post the result of lsusb again.

Turn off automatic updates in win so they happen when you want not when MS want.

Here are the camera details, and I don't use Windows and very rarely login to it and auto update is not enabled.

Re: Laptop camera is not getting detected LM 20.1 ( no device found error)
It was turning off fast start in win10 that fixed it. With fast start enabled, win never really shuts down. Among other things it will leave any windows partitions on your drives locked and read-only to linux. And as you have found out, it can block access to some devices because they are in use by win and not available to linux.
