Found problem if signaltap capture memory is 2048 bits or more. (can't do 8x256 capture)
This cause is failing error message "Invalid data received". Under 2048 bit seems to work.
Has anyone tested big signaltaps with emulated blaster or real USB blaster with Vidor.
I have official drivers because I also use terasic USB blaster for other cards.
