I am using the same H77 chipset, not the same board, and did not have to add anything for the USB specifically.
I have a Toshiba 1tb USB3 drive that I have tested on both USB ports, and additionally tested against the USB2 ports. I have no problem with that drive at all (the only USB3 device I have on hand) and the OS accurately identifies the protocol of any other devices I plug into the USB3 ports.
I have tested speed as well to see the Toshiba drive runs ~3x faster on the USB3 ports than the USB2 so they are obviously being supported without any additional kext's or editing of anything.
**I am using an extracted/optimized DSDT file though.**
It would be a bummer if there was any difference in the mobile version. I have not seen any kexts or edits to provide USB3 specific support for the x77 chipset as ML already supports it..

I haven't found a solution to the USB 3.0 issue unfortunately. I did however notice that it behaves much better with OS X 10.8.2 than previous updates. Plugging a device into the USB 3.0 ports still crashes the computer, but not immediately. I just use the two USB 2.0 ports on mine while booted into Mountain Lion. It could be that the mobile chipset isn't exactly like Apple's in the Ivy Bridge Macbooks, thus it's causing issues when loading kexts for the XHCI USB controller. Just a wild guess though. Reverting to DP kexts didn't fix the issue sadly. It just broke all of my USB ports completely (USB 2.0 included).
Tinker, I think I replied to your blog. I'm having the same exact problem.

I don't know if USB3 really works as I don't have any USB3 devices, but the ports do work as USB2 without any 'freezing' effect.

I got my USB 3.0 ports to accept USB 2.0 devices by removing the XHCI plugin from IOUSBFamily.kext. I will try a few different configurations later, but this lets me at least use all USB ports on my laptop now! It seems to be an issue with the XHCI plugin that I will have to resolve later.

Could you attach your XHCI plugin kext? I'm not seeing a way to add that device ID. Also, I tried installing PXHCD.kext and it doesn't provide USB 3.0 on my laptop since the laptop's USB 3.0 controller is an Intel controller.
I added the 1e31 ID to IOClassMatch in the XHCI kext to replace the one that was there. I forgot to mention that I also installed the PXHCD kext which I found on this site for USB3.

There are two version 1.0.8 and 1.0.10... and i noticed that only one work for me. did you try both ?
Also, instead of PXHCD.kext you can try CalDigitFastIO.kext and CalDigitUSBxHCI.kext. (you may have to use IOUSBfamilyRollback with)

Also, for me at least, plugging something in to a USB 3.0 port freezes OSX, but if I remove the offending USB device and wait a minute, OSX works again.
