Microsoft Corp. LifeCam HD-3000
The camera is super dark, only some kind of light source is visible.
On windows OC, the brightness is normal.
I tried to fix it in guvcview - unsuccessfully.
I looked in Discord, in Cheese I don’t find the device at all.

Here’s what gave hwinfo --usb

Hi, if you still have guvcview, how about disabling Exposure, Auto Priority (uncheck it), then adjust the brightness. Is there any changes? You could also lowering Power Line Frequency.

You could also try to reload the module uvcvideo with:

# First, remove it
sudo modprobe -r uvcvideo

# Load it again
sudo modprobe uvcvideo
4

Now it is not recognized anywhere at all.
And hwinfo now does not display the 12 point with the camera. (11, and then 13)

5

Is it after sudo modprobe uvcvideo? Or without doing anythings?

6

after

There are two modules need by your device to work snd_hda_audio and uvcvideo.

The above commands I shared, we remove the uvcvideo with sudo modprobe -r uvcvideo and than load it again with sudo modeprobe uvcvideo.

If because of two commands above you can’t connect to your webcam, you can reboot your system. The modprobe will not persist since we not create specific configuration inside /etc.

I apologize for such a long answer.
Restart did not help, it will not connect to the webcam

Thank you for trying to help

However, I’m feels bad. I just want to make sure that nothing bad happen after running above modprobe commands, are this device still work with Windows?

Get well.
It works, without problems on Windows.
