- cgminer uses its own version of the HID driver (Zadig). So in order to use cgminer you have to trick Windows to replace the driver for a particular device with Zadig's.
I hate to be pedantic but this is not quite true.

The device talks USB while HID is a driver designed for user interface devices like keyboards and mice, so when using software that uses this driver, it goes device -> usb -> hid driver -> software. Zadig is not actually a driver; it's a utility to tell windows to remove the driver and use the microsoft direct usb communication protocol (effectively a Microsoft driver called WinUSB). So while WinUSB appears to be a "driver" it's actually telling windows to just give the raw usb data to the software. So software that uses WinUSB (like cgminer which uses it for every single USB device) is talking directly to the usb device, bypassing the need for any driver, so it is going device -> usb -> cgminer.

Having said that, we don't have support for 2+ chip nanofury based devices, but VS3 is kindly sending me some devices to add support to cgminer, thanks!

I just tried 4.3.3, still running at half speed.
Any indications of when CGMiner will support full speed for NF2's?
