whatever OS, hubs and setup
that's very strange - my newest experience is
the same:
- Computer
- Hub
- Moonlander Stick
- OS
- Temperature & fan location
- mhz & core voltage
- usb cables
- mining pool & settings
but: i start bfgminer - sick after seconds, ( i have a *.bat file to start the miner on windows where i actually use it)
->quit and restart immediately - runs since yesterday for approx 20 hrs
so whats up now? voltage ups and downs in the local electricity grid?

thats absurd, there must be a reason imho

a loose connection in any wire? I didn't even touch one while doubleklicking on the executable batch file ^^ yea except the one of my computermouse. most wires are as new.
the only comprehensible difference is the position of earth in milky way

maybe a solar flare
the point is: I start the bfgminer twice under exact same circumstances, once it went nuts and another time it works

greetings
