Update to BFGminer 3.10.0
I am using 3.10.0, that's why I'm confused as to why it won't read any devices. I know they all work because cgminer is working.
You need to uninstall the CG drivers that came from zadig
have a look at the BFG readme files
I uninstalled the Zadic drivers, and rebooted and Win 7 took me to Si Labs for the driver for the U1 device and I installed that without doing the Zadig part and still BFG 3.10 would not load hangs and does not work. If you don't install the Si Labs driver Win 7 would not even recognize the U1 so that has to be installed, at least in Win7
This is all I use in my bat file:-
bfgminer.exe --set-device antminer:clock=x0981 -o

21.5Gh at the pool steady as a rock.
My drivers auto installed, but I did have erupters already installed.
