Why I wrote #USBLib and why I don't work on #Develop instead? The answer is as simple as obvious: Chamaeleons. I'm getting two Furcifer Pardalis (Pantherchamaeleons) and I want to give them summer/winter cycles. Therefore I needed a control unit ... in my case an old PC does this job. I used the SIS-PM from Gembird (http://www.gembird.com/) a programmable USB power switch (In germany you can get it from pearl). If you're more interrested in chamaelons (but you need to speak german :)) you can visit my page at ambanja.homelinux.org. There you can download the control software too.
