The latest cgminer doesn't work at all (not even for block erupters, and yes, tried without them plugged in also) it just says "failed to initialise" / "you need to install a WinUSB driver for - BF1"
I have tried versions 3.7, 3.6.6, 3.5 and 3.4.3, to no avail
Well the instructions are pretty clear. Cgminer won't work till you install a winusb driver for any USB devices. The instructions are plastered all over the README and ASIC-README files.
I followed these instructions, installed the winusb driver with the aid of zadig, the BF1 device was correctly identified in Device Manager, but Cgminer 'refused' to detect it....

Try cgminer 3.7.0 that issue with detection should be fixed now.
