It connects to PC via a USB port and to the video card via a HDMI port. I actually plugged in the AC adapter just to make sure the juice is always flowing. My DK2 stays plugged into the PC 24/7, I had to reboot PC once, after leaving DK2 off overnight, it wouldn't power until i rebooted (the unit would power up, but the display was black). Never had any power issues otherwise. I disabled PC control over the power to my USB ports via device manager too.

I shorted out a usb and it fried my motherboard. So it is possible.

I won't say this is impossible, but I do think it is HIGHLY unlikely.

It's possible, but it's not going to be the norm. My guess is that there was something wrong with that DK2. Product defects occur. An excessive current draw should not be an issue as the USB ports are current limiting, but certainly a short can cause some issues.

I wouldn't take this as ANYTHING to worry about.

If true, this is a sad story but I don't think it is common or very likely to happen for most people.

Certainly nothing to worry about. It's possible that the USB ports were defective, or that the Rift itself was defective. I would lean more towards the former. I work with computer hardware for a living, and I can't tell you how many times I've seen seemingly fully functional computers running on what I could call ruined capacitors, or on other various wrecked hardware. It's not too far fetched to believe the user of that now broken computer simply pushed a breaking PC over the edge.

Maybe there went something wrong with the usb plug, being mounted upside down or something...

So you think 2 laptops and one pc die, or at least the usb died, when he plugged in the dk2 - because they all had already a hardware problem? 😄

I didn't read his post, to be honest. I'm just stating that it was likely a problem with either device, rather than a problem with a normal DK2. It's also possible that the guy was lying to shame the DK2; Kotaku shows us that some people just hate the Rift for no good reason.

A short-circuit at the rift end shouldnt have cause this,
The USB standard requires that all USB powered devices have over-current protection, usually in the form of a polyfuse.

Odss are the pc host side has failed and somehow chucked a bike voltage spike down one of the two data pins.

*edit

I didnt read his post properly. looks like the rift its self is probably ok.
