Rant - Problem booting with USB device connected.

WTF!
So i'm at work, and i have my cell phone charging off the usb port. Pretty innocent.. well at least you think it's innocent.
I make some changes to my registry and system files.. To be safe i need to reboot my machine.
Reboot...
Poof> The PC does not want to start up again.

So, i try and reboot again.. Thinking that maybe i didn't press the power button hard enough.. nope, same error.

Well, i take the walk of shame down over to IT. Nobody home..
I come back ranting and raving to my very knowledgable co-workers of a nice little bug with USB that they have experienced in the past.

Their intel leads me to unplugging my phone and rebooting my PC.
Presto, that did it. Everything is working fine again.

A bug with USB and booting your pc? C'mon.. isn't every single device that comes out now only in a USB form factor?
I can't believe that.
