I recommend getting a Raspberry Pi and installed Minera, super easy to use.
This is my best recommendation I can give. It has the propertly built versions of cgminer; and it even has easy places to drop config lines in the web interface; it also restarts dead miners, etc.
Check out MinerA. 100% worth the effort when it comes to the older gridseed devices. Its what I personally used to control many many many orbs and blades in the past.
But yeah; dont expect any real profit from a g-blade these days =)
