K70 RGB Broken USB controller/bios because of K70?

Figured it was time to retire my old G15 keyboard, so I picked up a K70 RGB. Now, for the past 2 days I've been trying to fix my computer. Let me recap what happened. First of all, I should have read the instructions or at least the quick guide, because what happens next is my fault. I plug in both USB ports, not paying attention, to which one I plugged in first. The K70 lights up beautifully, when all of a sudden I get a BSOD! After that, every time Windows loaded up, it would BSOD. So, I unplugged all my usb devices and my computer booted up fine. What was weird, was that I could plug in an old Logitech usb mouse, and it worked fine. No crashes or anything. Plugged my G15 back in, and BSOD. So, I updated my bios, and my computer didn't crash even with the G15 plugged in. Plugged in my sensei mouse, and right after windows installed the driver, BSOD. I called Corsair support, and the guy flat out told me to call my mobo company, and that there was no way the K70 caused those problems. But, the only thing that I installed recently WAS the K70. Could I have messed up my usb controller, when I plugged in the K70 in the wrong plug order? Why does my computer crash, while installing usb drivers? I don't know what to do at this point. Please help.
