What are you guys using when there is more then one COM in the double digits? This was my best idea and it's not working
-S COM8 -S COM9 -S \\.\COM10 -S \\.\COM11
cgminer should automatically see BFL devices by itself now, unless you're using something else.
Also, I think 2.6.5 is in the spot for 2.6.6 @ "cgminer-2.6.6-x86_64-built.tar.bz2".
