I just got my 5Gh/s miner today and using Win 7 64bit I was able to plug it in, it installed itself automatically (on a Com port) and I could start mining just fine with bfgminer.  

I want to use cgminer (mainly to use the java API stats to see what my unit looks like) and followed everything I can find on using zadig to replace the drivers with the winusb drivers but every version of cgminer I've tried says "No USB devices detected.  Waiting for USB hotplug devices or press q to quit".  It shows up in device manager as a USB device as BitFORCE SHA256 SC and everything there looks textbook from what I've read.

I've actually moved through 3 different laptops with Win 7 64bit on them and they do the same, first time I plug it up it works fine with bfgminer, I replace the drivers with zadig and then it's nothing after that with either bfgminer or cgminer.  What am I missing here?
