How do I run several miners such as my USB stick litecoin/bitcoin dual miners and my Gridseed miners on cgminer.  Do I have to open up several instances of CG miner for each miner or can I run all of them off the same cgminer instance.  And when these autodetect how do they autodetect each one through each device driver you download when you hook them up...  Thanks so much for any replies I appreciate it....I hope this made sense.BTC I want to run everything off of one computer...

   is .08 kwh cost effective for bitcoin mining, also if its a business that draws lots of power it is .04 per kwh?
