Hi Con,

Firstly thanks for all the updates aimed at Hashfast devices, 4.2 has helped a lot.

As all Sierra's are not born equal I need to run them at different clock speeds. I successfully used the '--hfa-name Slug --usb 4:42' to rename one device to later allow me to use '--hfa-options "rabbit:650,turtle:550"'
If I add more renaming to the string it simply doesn't find any device. Can you tell me what I have wrong with the below?

--hfa-name NS1 --usb 1:7 --hfa-name NS2 --usb 2:7 --hfa-name NS3 --usb 2:4

Thanks
