Damn - I've just accidentally plugged my PC case's USB front panel connector into the IE1394_1 port on my ASUS M4A88TD-V EVO/USB3 motherboard. A brand new motherboard too. I obviously wasn't concentrating when plugging everything in.
The manual warns:
"Never connect a USB cable to the IEEE 1394a connector. Doing so will damage the motherboard!"
Now the only thing that I (briefly - ie for a few minutes) plugged into the front panel USB connector was a cordless mouse receiver - will I have really damaged anything?
How can i tell if the IE1394 port is okay? I don't use Firewire and I assume that's what may be damaged?
I'm having problems getting sound out from the digital output, but I think that's a config problem as I don't have a digital connection AND I can't even get sound from playing back DVDs (but other sounds are okay, such as from YouTube, Windows sounds, etc). So I hope it's not related.
