EDIT: I'm the plum that flipped the polarity on the 5v rail by using what I assumed was a standard pinout for cables that easily plug into one another. EDIT EDIT: Colour shift from grey to blue. Hi guys, Some of you might remember me from waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay back, and to those that are new, "hello". I thought its worth raising here an issue I've had with the commander pro. It would appear the 12V side of the device is failing to kick into life despite the presence of 12V. This results in the commander pro trying to power a 12V fan/'s from the USB bus, and thus over amps the attached cables burning off the insulation and letting the smoke out. I've been posting on the corsair forum, but its a little lack luster in terms of responses I've had. link link I'm now on a campaign to get my money back, and to spread the word of warning. Oh and their tech support makes the apple store employees look like actual geniuses! Customer: Hi your product just let the smoke out Corsair: Oh, could you plug it back in and see what happens? Customer: Hell no!
