Greets.

Just got another couple of 2Pac for my collection. But getting a problem with one of them not being detected. When I plug it in, the blue LED lights up, but turns off as soon as I let go.

I.e. if I touch the heatsink, the blue LED lights up. The USB bus sees it but shows as inactive. cgminer does not detect it. The other one runs fine. I presume I have a faulty 2Pac ?

Incidentally, they run months on end without intervention.
