Hopefully it doesn't lock up your box as soon as you plug it in. If it doesn't, try digging in /proc/video/dev and cat whichever file(s) are there. Sometimes you'll run into some information. > Are there docs identifing the proper driver?

However, you did say that you've determined that it's a quickcam express. You can find drivers for it at http://qce-ga.sourceforge.net/. Also, a decent list of Logitech cams and drivers available at http://qce-ga.sourceforge.net/bio.html . If you want to hack together something that deals with the compression the camera uses (so you can get higher frame rates and image sizes) some guy has reverse engineered the Quickcam Web at http://www.informatik.uni-oldenburg.de/~delwi/quickcam/ . It should also be noted that firewire at 400 mbps transfers some serious data, and that firewire 2.0 due sometime is spec'ed at 800 mbps. Cheers, Brian
