Thanks guys, i got it to STM32 to install now.
giving it some time, will report back when/if it works.
UPDATE: Okay got it to install, i see Virtual com port Stm, and the uart one in Universal bus devices etc.
but my Gridseed is flashing green in 1 sec intervals, and sometimes stays constant red, and flashes green, and just repeats.
nothing happening, no hashes being accepted.
