Well i finally was able to format a damn micro sd. It did the whole light show and i can log into it via firefox. I plug a asic into it and it sees it but wont hash.... could be because these are Jupiter boards or the asics are toast. Not worth my time really, need to find a ok working Neptune with at least one working die to see if these controllers are good.
I assume you're powering it down before plugging in a cube, right? Is it displaying stuff on the display, and is the green light on the side?
