hi can you help me solve
No Module named usb

./prog/usb-flasher/logitech-usb-flash.py bin/dongle.formatted.bin bin/dongle.formatted.ihx Traceback (most recent call last): File "./prog/usb-flasher/logitech-usb-flash.py", line 3, in <module> from unifying import * File "/home/zodiac/Downloads/nrf-research-firmware/prog/usb-flasher/unifying.py", line 19, in <module> import usb, logging, time, sys, struct, os ImportError: No module named usb make: *** [Makefile:33: logitech_install] Error 1

@Decapitater Did you use the code adjustments from @chadmiller ?

Try changing "python3" to "python" in the first line of usb-flash.py, seems to be a wrong reference to the usb module when using python3

Nevermind, there was still a reference to pyusb from a python2 library on my machine - got confused.
I am still running in the same issue as @Decapitater , will continue looking for a fix.
