Windows 7 - yeah wanna use CPU - where do I enter this line?

Hi Guys!

I am probably just too dumb, but I have configured my CGMINER but it just won't start.

It always tells me that it can't find no devices and that it wait's for an USB hotplug...

I just got a PC and Laptop that keeps running at my university for nothing (it has to be running) and I just want to use both for mining.

Pls help!

Cheers Stefan
