Yes, read post 76
I mean, has anyone patched the 10.8.3 kext and released it. If it works at least with the u720200(a) chipsets, at least it'd be worth trying out.
Also, since I haven't seen anyone SPECIFICALLY mention it......has anyone tried using a usb 3.0 hub connected to their USB 3.0 cards to see if you can plug in more than 1 external drive ? That's currently a limitation of the patched LaCie drivers, while they can see a USB 3.0 hub now, they won't enumerate drives connected to them.
