Hey folks,
I've been wondering if there's a solution to the problems of potential ground loop issues when you have ASIC miners plugged to a different circuit than the host device, or multiple different circuits.
Now I've only heard of this in the past when people have been plugging a monitor or printer into a different circuit and the ground loop through the interface cable causes erratic behaviour, even burns out parts on occasion.
Now, having a slight clue, I would check for DC or AC potential differences between the ground shields before actually connecting them.
This could also happen I guess in situations where you use multiple PSUs on one mining rig, such as in a BFL minirig or in a honkingly huge GPU rig, but the ground bonding between them should be a lot better, not being the shield of the USB cable.
Any thoughts?
