Quickcam Communicate STX under Linux

Some days ago I bought the webcam Quickcam Communicate STX from Logitech. The reason why I bought a webcam is simple: My girlfriend is having english classes for 2 months far, far away in ireland.
We will miss us each other and I promised to mail her every day a photo of mine to keep her in mind that I love her. It’s just to shorten the distance between us a little. I think a webcam will fit this challenge quite well. After a lot of hours trying to run the webcam under linux with a tv-card I found the tool webcam what repeatly makes a snapshot after some times and loads it up on my server by FTP.

Get running the webcam Quickcam Communicate STX under a Linux/Debian system is quite simple if you know that mysterious thing about the USB port.
First of all you need the driver spca5xx what supports the Quickcam Communcate STX. Just follow the instruction given and you’ll have no problem.
Now you can check with dmesg if your systems recognizes your webcam by plug it in. If you see some lines about a your webcam than you’ve won.
Test with camstream if you can get some pictures out from your webcam. You should see the blue light on the top of the webcam and a kind of blinking when it is called by your linux system. If you still have problems check the USB port where you plugged your webcam in. If there is a second device on the same port, just change the USB port of your webcam to a free one.
The reason is that the two devices share the bandwidth of the USB port but the driver wants the hole bandwith. That’s the big mystery about the webcam. I needed some days to find out this kind of problem.
