Hi there,

same symptoms for me in Minera/Pi3/2Pac
I do not think something is missing.
after restarting the Pi3 I un/replugged the 2pac, activate the miner
it started to mine @3gh the the rate was falling until 0, in 3 minutes
it could be caused by the fact that my stick is plugged directly on my Pi3 and have no additional param to set-up the freq
(alos note that the light on the stick is green, always, do not know if it is normal)
thanks to all of you

Bye
