I have a normal usb 2.0 cam. Connecting it to my pc, it works perfectly. It is not working with my raspberry pi (2). I had installed motion and it had worked good before 2/3 weeks when I tried it but now, it says

[1] Retrying until successful connection with camera

[1] Failed to open video device /dev/video0: No such file or directory

When I run:

sudo modprobe bcm2835-v4l2 It gives me:

ERROR: could not insert 'bcm2835_v4l2': Operation not permitted

I searched up much but did not find a solution. When I run:

vcgencmd get_camera

I get:

supported=1, detected=0

What can I do?

Problem Solved!!

What I did was:

1) Removed Motion from Raspberry Pi using

sudo apt-get --purge remove motion

2) Disabled Raspberry Pi Camera in raspi-config and rebooted the Pi

3) Installed fswebcam using

sudo apt-get install fswebcam

4) Tried capturing a photo with it using

fswebcam -r 640x480 --no-banner image3.jpg

5) It worked!! Then Installed Motion and tried streaming it and that also worked!!

This is the solution...

  • I am stuck at your point 4. When I enter that command I get a no such file or directory error for /dev/video0. I am running on a raspberry pi zero with raspbian. Running "sudo modprobe bcm2835-v4l2" does not output anything

  • @JRsz Did u try reinstalling motion? Starting from the first step? Make sure you reboot your Pi before installing it again. It worked for me! I was stuck at "no such file or directory" for a couple of weeks! This did work for me... Try reinstalling Raspbian if nothing works Aug 13, 2018 at 13:09
