OK. I Manually downloaded the gspca-source module and did 'm-a update' and when I went through the steps it seemed to build OK, but did not load. Silly me! Once I unplugged the camera and re-plugged it in, the driver loaded just like it ought to. At least is seems to have done so. Running lsmod shows the gspca module and a few other new modules.

I didn't have the kernel headers for my 2.6.16 kernel and they do not seem to be available in the Etch repository. I took this as a sign that it was time to upgrade my kernel and upgraded to 2.6.22-3-k7 from backports. Then I reran module-assistant. This time, m-a found and downloaded the kernel headers. I then selected the module to compile. The gspca-source was not listed, so I used the spca5xx-source. When I tried to build the sources, however, the build failed. The logfile contained nothing but the date and time, so I have no specific errors to report. It may be that the problem is using spca5xx-source instead of gspca-source, but that was not listed as an option. If I download it manually, might m-a find it and allow me to use it. Any ideas on what I should try next? -- Marc Shapiro mshapiro_42@yahoo.comMarc,You have a couple of options, one is to upgrade your etch to the current 2.6.18-5 kernel and then build the spca module. I built the spca module from source with 2.6.18 kernel.The spca5 source doesn't build with the newer kernels 2.6.22. You need to use the gspca-source.I am running testing/unstable, and gspca-source is available in testing/unstable repositories. If you grab the 2.6.22 from backports, they might also have that source package. Otherwise you could just grab it from a debian repository or use apt-pinning to pin a lower priority for lenny/testing and and then grab the gspca source.I am using the gspca module for my web cam, so do know that the module builds with 2.6.22.John

Now, how do I access the camera, so that I can capture an image to be processed? I am currently thinking of using opencv through either C/C++ or Python. How would I access the camera to generate an image (probably jpeg) that I could then save to disk or, preferably, pipe to opencv?
