I had strange problem with my EyeToy which meant if I plugged it in before and then booted the slug I would get the following error when I tried to start webcam

v4l2: open /dev/video0: Device or resource busy
v4l2: open /dev/video0: Device or resource busy
v4l: open /dev/video0: Device or resource busy
no grabber device available

However if I plugged it in after it had booted it worked fine. Thus I did the following….

fuser /dev/video0

/dev/video0:          1871m

ps -aux | grep 1871

nobody    1871  0.0  2.4   5492   732 ?        S    19:55   0:00 /usr/bin/camserv

This showed me that the software camserv was trying to access the dev. After reading this I had a ‘Ahhh now I remember moment’ i’d installed a few webcam software when I was looking for the right one amnd not removed it hence the conflict. All is working as it should now.

I only needed a simple webcam solution so I’ve used one called ‘webcam’ installed using

apt-get install webcam

this creates a config file /root/.webcamrc edit this file to suit your needs. Here’s mine for my own reference….

I’ve managed to get a couple of cams working on my slug so here’s what ones and how

Logitech Pro 3000/4000

apt-get install qc-usb-source qc-usb-utils

Logitech Quickcam Chat

module-assistant auto-install gspca

EyeToy
