Asus M3N78 Pro USB problems

Since the day I got my Asus M3N78-pro motherboard, the USB ports have all been flaky. It seems that items with batteries or needing alot of power (ipod, wd passport) don't work -- whenever they're plugged in, it constantly connects/disconnects the devices over and over. I've tried several ipods and a few WD passports and nothing works. The mouse/keyboard and thumb drives work fine.

I'm running:

m3n78 pro
phenom x4 9600
4gb ocz ram
geforce 7800gt

I'm going to try flashing the bios to see if that works, otherwise i assume I need to send it in for a new one?

annnnnd the asus EZ flash thats onboard keeps saying each .bin file i download from asus for the update "doesnt contain boot info", something like that. this=huge PITA

I have this issue too, so please post if you find something

I had a similar problem. I thought it might have been the USB headers on the motherboard, but i found out the two top ports on my Case were worn out. I connected the header to two other USB ports and they seem to work fine. However I am getting the occasional USB "bandwith exceeded" issue. Anyone else having that problem with this?

I have the EXACT same problem, same motherboard. My iPhone and my iPod touch were both syncing just fine for the first few months, then all of a sudden out of nowhere both Apple devices will connect & reconnect continuously. It actually makes the iPod Touch restart itself. Incredibly annoying.
I also have a USB wireless network adapter that is 802.11n....haven't tried unplugging that and attempting to user iPhone iPod Touch, will try that and post later. I see that there hasn't been any activity on this thread in quite some time. Has anyone else figured out a solution?

I have the same mobo and the same problem. I get about this far in any similar post and then everything goes silent. What's the deal? Has anyone figured this out?

I bought a USB board thinking that the USB ports on the motherboard were the problem, but that didn't change anything. I've reinstalled the drivers etc.

I saw another post that indicated a xxxusb driver in system 32 folder was interfering; not sure. Please let me know if you have found the solution short of getting a new motherboard.

Thanks
