Logitech C270 webcam not detected with custom kernel config (5.10.9)
Let me make this straight and simple:
I compiled my own custom kernel and set the options using "make menuconfig".
Here is my .config file
I cannot seem to figure out why zoom, discord, and a myriad of other applications (pretty much all) do not recognize my Logitech C270 webcam. I booted into the arch generic kernel and they were detected just fine, but with the custom kernel, no matter how many options I compiled with, they would never seem to work with the camera.
With the custom kernel lsusb detects it, there are no errors associated with the device, and there seems to be a weird thing with
lsusb -s 001:004(001:004 is the ID of the camera in lsusb) where it shows no output when I execute the command.
I have been looking tirelessly online to figure out how to get it working with no luck, so I feel I need to make a new topic about this. I do believe this is a driver issue or a kernel config issue, but I just cannot seem to figure out WHY it is not showing up.
Thanks in advance!

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
Have you compared the loaded modules between the two kernels after using the webcam?

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
I tried to check but there are so many modules loaded in the default kernel that it's completely unrealistic to try and pinpoint the specific module for the camera. I even tried looking for modules related to cameras but no luck.

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
Please post the output of lsmod from the default kernel. On the custom kernel was ov2640 module loaded? gspca_zc3xx is built in on the custom kernel so can not check using that module.

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
Just posted the lsmod from the generic kernel. Sorry for the confusion about that

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
Is your not just a problem due to the new kernel? THere is problem with some logitech webcam. I had to downgrade kernel. I suggest you get a look at my post about that:

Re: Logitech C270 webcam not detected with custom kernel config (5.10.9)
Most cameras use the uvcvideo module.
If you install usbutils and run usb-devices, its output includes the driver used for each usb-device.
