USB webcam (Logitech C615) not detected

chro · 05-15-2016, 06:22 PM

My Logitech C615 has stopped plug & playing, and I think I need some help with drivers...? Something appears in my lsusb and dmesg results when I plug the camera in, but it's not initialized, no /dev/video0 is created, and I can't use it. I have used this webcam on this system many times before, and don't know what has changed.

Very similar issue to this (unresolved) thread: http://www.linuxquestions.org/questi...ed-4175465187/

Kernel version (uname -r):

Code:

3.13.0-83-generic

The camera shows up in lsusb as:

Code:

Bus 001 Device 008: ID 046d:082c Logitech, Inc.

These lines show up in dmesg when I plug in the camera, but nothing more:

Code:

[ 1024.200077] usb 1-6.3: New USB device found, idVendor=046d, idProduct=082c
[ 1024.200081] usb 1-6.3: New USB device strings: Mfr=0, Product=2, SerialNumber=1

Hya,

Did you check lsusb or lshw? Make sure that correct driver is present.

cheers

Hi, thanks for helping.

1. As I mentioned in the original post, the webcam does show up in lsusb (lsusb -v produces ~1300 lines about it)

2. I don't know what the correct driver for the webcam is; I'm operating under the assumption that it should be included in the kernel, because I never had to install any device-specific drivers for this webcam previously.

3. The internet suggests that the linux driver for this webcam is 'uvc'; how would I go about checking that it's installed and working properly?

Edited to add: output of lsmod

Hya,

Check lsusb -v, lshw, and look for configuration and driver.

If uvc is the correct driver, it is missing in your lsmod.
Try "find /lib/modules -name uvc\* -print" and if module(s) exist.

cheers
