I had to do it more than once.
All the time my PC couldn't show any Port in the Arduino program: Tools -> Ports (Ports was displayed in grey)
I got this error: "COM 6 does not exist" in firefly
So it was obviously the USB connection. My flatmate told me that Windows USB Ports seem to have this problem of not recognizing devices more often...
Hope that was helpful,
cheers…
I am not sure if that's the file. Horster camera control has a tab with 3 components in my pc. I cant recall if horster tools had bundled camera controls with other tools.
