Das Problem liegt tatsächlich am connective, ist mir im club auch schon passiert, dass einer einen Venitilator eingeschaltet hat und nichts ging mehr.
Das Problem kann aber behoben werden:

This WILL definately void your warranty! And you need to know how to use soldering iron for it! Although, this is REALLY simple.
As an electronic developer with experinence I wasn't satisfied with a such behavior of Conectiv. I've opened it and inspected the pcb. First of all - big up for m-audio! Routing of pcb is GREAT! Except some things like routing signal from mic preamp all around the board Smile But in such a crowded board, I believe that was one the best solutions.
The carsh occurs when power spike occurs - it just freeze the controller. So first solution to think of is to increase capacitance of the filtering capacitors in power-filtering part. Huh? No serious filtering for USB power? Yes, according to standards it is not needed, 'coz every PC must have good filters inside. So it's not an m-audio fault.
On the other hand DJ's equip must work as a tank in any conditions... So I've started to search the place to put some extra caps on the board. Bad idea, actually Very Happy It's easier to solder cap on the other side of the board, straight on the USB-connector pins. And that's what I did - I've glued one SMD 220uF 10V (tantalum) capacitor near to connector and with wires around 5 mm solder it directly to pins. Of course you can put not-SMD cap, but I didn't have the small one Laughing
For now everything works perfect. I've tried hard to crash it with plugging-unplugging powerfull stuff into the same socket with PC. Well, IT IS A SUCCESS!
USB pinouts can be found on internet. (and always remember - square pad on pin is ground, or negative pin of cap!) Or if anyone like it - I can post a photo of it, so you can clearly understand where to solder.

ansonsten sollte die betroffenen bitte hier ihr Leid klagen, M-Audio ist an der Sache dran aber es gibt noch keine offiziellen Aussagen:
