In the process of troubleshooting a webcam problem, I stumbled across a cool little utility called sane-troubleshoot. It’s a simple GUI app that scans your system and your SANE scanner settings and lets you know if there are any problems that you need to be looking into, including configuration, permissions, and the software itself.

Installation couldn’t be any easier; in fact, there really is none. You simply download the tarball and unpack it, then run make in the unpacked directory. This compiles the software for your system, and then you run the new executable from the same directory: ./sane-troubleshoot.

Unfortunately it told me everything looks good for my webcam, so I’ve still got more digging to do. Everything connects to the cam and I can turn it on and off just fine, I just can’t get any images. Guess I’ll have to keep digging.

But sane-troubleshoot looks like it does a thorough job, and it eliminated a fair chunk of my troubleshooting. If you’re having troubles with your scanner or webcam, then give it a try and see what it tells you.
