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....
