Okay i've read Alot of back and fourth banter about How the Jalapeno BFL ASIC will be powered.
Some say it will (need) use 1 USB connector
Some say it will use two USB connectors, As a safeguard.
Some say it will use a DC barrel plug to power it
Some just say "its USB POWERED jackass"
Some just say "USB power has a huge limit"
To double as a coffee warmer, I'm leaning toward wall.
