Two of six USB3.0 sockets having issues

I recently installed a Gigabyte GA-Z77X-UD3H motherboard, which has 6 USB3.0 ports on the back panel (no 2.0 ports). I'm running Windows 7 on it.

Two of the six USB ports are having some issues - specifically:

USB headphones - When I plugged these in, the sound cut out intermittently. I thought it was just stress on the connector from bending around the tower (they were a cheap $30 pair, almost a year old), so I plugged it into the 2.0 ports on the front and it worked fine.

Mouse - Stops responding every so often for a few seconds. Actually, as I was typing this (and testing those ports to make sure) it stopped responding completely and I had to change the port.

Keyboard - Repeats a key input for ~1 or 2 seconds every so often, like I'm holding down the key. For example, I'll press 'k' and it'll just keep printing k until it gets itself together again.

These all seem to be somewhat similar issues so I figured it was those two ports. I'm hoping it's not a hardware issue, so does anyone know which drivers exactly I should install? I already installed all of the drivers included with the board. I know Windows 7 doesn't natively support USB3.0 so that might be causing an issue.

This thread mentioned a similar issue with the same board and OS. I installed the VIA drivers linked and as of yet haven't had any more issues. I'll keep an eye on it, hopefully that fixed it. It sounds like some of the ports are Z77 ports and some are VIA ports (I have no idea what this means), and the VIA ports' drivers were out of date. edit; As per this site the Z77 chipset supports up to 4 ports, so I imagine I chose the two not supported by the chipset. Other factors (for example, using the mouse/keyboard in those ports does not wake it from sleep like the others) convince me that this is a different set of ports with a different driver. Updating it seems to have worked.

I don't think a BIOS update is needed. None of the BIOS versions newer than the one I have seem to address the issue.
