What happens if a 1394 cable is plugged into USB header on mobo?

I accidentally plugged in the 1394 (Firewire) cable from the case front panel into the USB header on my motherboard. The PC was completely off at the time. I have since put the cables into the correct headers.

Would anything bad happen to the PC?

Not if it was off, even if it was on I don't think it would do anything if you didn't connect a firewire device.

Nope. Shouldn't have done anything at all, even if it was on.
