I have an velleman K8055 and when i put it in my pc (windows 7) the Power LED is ON, LD8 lights on, then off and stays on. So i tried it on an other pc (vista) and everything works perfect.
I also looked at USBview.exe and the kit device buss speed was Full
The kit works perfect but there is something with the USB driver on windows 7. How can i make it work?
