I hope the NF* variants have a unique identifier on USB to make them easy to distinguish on USB.
The nanofury currently nicely identifies itself as:
iProduct 2 NanoFury NF1 v0.7
Managing variant devices is much easier when some forethought goes into it by the hardware devs thanks

I can send you my code if you like. I modified cgminer 4.2.3 for NFx already.
I get the number of chips by finding "NFx" where x is for chips, i.e. NF1 for 1 chip, NF2 for 2,
NF3 for 3,...NF5 for 5, NF6 for 6...and so on...
The freq of all chips are the same. I have no idea to add an optional to set different freq for each
chip. As the picture I showed that is tested on "NF3".
Later, I will show NF5...
I would be intrested in the code if youd like to share it, id like to test it on the h-card-usb thing.
Just point me where i have o change the numbers.
