I will remember that.
I am using zadig for the cgminer 3.10, but that program refuses to accept the bmsc options as adding it to the command line makes the command window to appear for a second and disappear.
Perhaps that was the problem.
I will try the BFGminer 3.10 with the Silicon Labs cp210x USB to UART Brigde drivers first and work my way down the versions.
Thanks
