I've got a new Z77 Extreme 4 in my build and everything works perfectly with the possible exception of the USB3_34 header. I have a 3.0 Seagate Backup Plus Portable that I know works perfectly from tests on friends machines and other ports on this build, but it is very unstable on my front ports. It will run for some time under low data transfer but if I leave it running to long or I transfer a large folder it stops working. Sometimes Windows complains it can't find some of the files and other times the copy goes very fast and ends up having only the folders and a few random files instead of the entire copy. Every time it fails the led on the drive turns off.
The ports themselves run fine with other USB 2.0 devices, but unfortunately I don't have another 3.0 device on hand to test with.
I'm pretty sure it's a power issue since all the symptoms seem to fit. ASRock support suggested a new cable and so I'm waiting on one from Rosewill (who by the way has awesome support) and I've ordered a small adapter to make sure cable length isn't the issue. I'm pretty sure the cable was fine though considering both of the splits exhibited the same symptoms and USB is rated to 5 meters so unless the whole cable batch was screwy I think that's a dead end.
I've been scouring forums for about a week but I can't seem to find anything.
The notion I'm entertaining at the moment is that either the board is not supplying enough power to the header or that the header isn't specd to supply the same amount of power as a normal 3.0 port. Does anyone with some data sheet skills have any idea if that might be the case?
