Problem with usb cameras -how to make template?
« on: April 04, 2009, 11:04:37 pm »

Lets start this question with the fact that i am absolutely new to linux and lmce.. But I like it!

As I have three usb cameras, and can not get any of them to function, I would really be happy if someone could help me, and explain exactly how to make a template for the most advanced of them, the Qeye that is so nicely fitted into my new BenQ M2200HD screen. And yes, I have tryed to use every thread i could find here, related to this.

The camera has, according to the output of "lsusb -v" a built in microphone.  Could one use this output in any way for the template to get the camera working?  I have spended most of two days trying to make a template on my own, and yes it loads alright, pnp-finds the camera by vendor id, but how i try i never get any picture from the camera..

..Any help are welcome..
Thanks in advance!

You will need drivers for the camera under linux and then you just use the generic usb camera template controlled by motion wrapper under linuxmce.

Unfortunately, there are quite a few cameras that do not have drivers - but they may still show  up in lsusb.
Your best bet is to to check dmesg to see if a driver has been loaded. It will usually create a /dev/video entry. If it has that then just follow the wiki pages for setting up generic usb camera.

If drivers have not been loaded for you camera they may just need to be loaded. Google your camera and linux to see what you can find out.

Thanx for new commands I did not know existed! =)

This lines in "dmesg" output indicate that this camera got a driver loaded:

[   67.528719] Linux video capture interface: v2.00
[   67.667196] uvcvideo: Found UVC 1.00 device QEye 2.0M pixel (04f2:a142)
[   67.668368] usbcore: registered new interface driver uvcvideo
[   67.668420] USB Video Class driver (v0.1.0)

But there was no "/dev/video" in the output (From the MD, where the camera are attached)

And I have done some googling already, and tested every solution suggested in wiki / forums that seems to be related.
..been stuck with this for almost 48 hours..  =)
