Hi guys!

I have two Avalon 290Gh modules, bought them recently. Mining with Raspberry Pi. Now one of avalons stopped working - one LED inside is constantly on (third one from the left). Funny thing is - when I switch USB connectors (I mean this things) from one Avalon to another - problem is following connector, and another Avalon stopping. I'm sure about my PSUs, tried several of them. Can the problem be in the USB connector itself?
