Good evening.

I'm not familiar with Virtual Box, but I understand it's something like VMware from what I see on their site.

If virtual box is recognizing the webcam, what happens when you plug the webcam in while observing the output of tail -f /var/log/messages in slackware? If you don't see camera recognition in some way or some special drivers for that camera being loaded, then we can tackle that issue.

You will also see the camera name with lsusb. All of these commands are as root. Let me know what happens with those commands. If it doesn't work out, then we have to see what drivers your camera needs and whether or not v4l is compiled into the kernel. I know that on 12.1 the v4l drivers are available by default (on my full install, at least). If the v4l drivers are available, then you should look into the webcam drivers.

This is all on the path to seeing if the camera will work in Slackware, but as for that other O$ M$ not recognizing it... I'm not sure how to fix that.

I would just scrap the whole virtual box and XP thing and run slackware 12.1

Just kidding.

Thanks. I haven't searched the web for those codecs yet, but will you please:

1. run tail -f /var/log/messages as root
2. unplug the camera
3. Plug the camera back in
Please paste the output of tail -f /var/log/messages and lsmod here. Also, will you also post the output of lsmod?

This will help see if the drivers are being loaded for you. After we find this out, we can tackle new horizons.

Peace,

Looks like the webcam specific drivers and the v4l drivers aren't being loaded. I have to go to work, but in the mean time see if the the v4l drivers are available as modules. Aside from trying to modprobe them, lets just see if they exist:

locate v4l

Also, we can use the device id of your camera and its name to find out what drivers it needs or if they are available in the kernel to be built as modules. ID 041e:4041 Creative Technology, Ltd WebCam Live! Motion.

I would search for the 041e:4041 linux on google. And if that's not helpful, try some different search strings.

Keep us posted on your progress.

Thanks,

svn: Can't connect to host 'svn.berlios.de': Connection refused

where do i get a tar.gz of v4l

You have to recompile your kernel or get a new one and enable v4l as modules. Here's a kernel compile guide someone recommended to me:

http://alien.slackbook.org/dokuwiki/...kernelbuilding

You will see options for some cameras in the config list, too.

Good luck,
