Yes. I have two usbasp's and tested the firmware with one of them -> works great.
Now I have found out that this only happens, when I use a hub. (scared of a damaged notebook usb port^^)
If I plug it in directly then nothing happens. -really nothing....
If I unplug the µC then Win7 announce an unrecognized device.
