USB 3 speed issues - Asus GA-Z77x-up5-TH

First off, I apologize if I'm not in the right forum section.

 

So my Hack is working pretty much perfectly, aside from a few kinks. One of these is really starting to bother me: USB 3 speeds. My actual ports DO work and I can plug in drives and peripherals, but they write at USB 2 speeds (although read speeds seem just about at USB 3 strangely enough).

I'm using an Asus GA-Z77x-UP5-TH with Mavericks, Intel 3770k and nothing else too fancy, on Chameleon. I installed the generic USB 3 controller, deleted AppleHPET.kext (which fixed the front port not working at ALL) and all my XHCI settings are, from what I read, correct (XHCI=Auto, Pre-boot=Enabled, Handoff=Enabled).

Does anyone have any idea what's going on? This is really driving me nutters... and I'm starting to obsess over it something mad!

Thanks!

Hey thanks for the reply.

 

I've been contemplating going to Clover, but a) I'm a bit put off by the work it seems to require and B) aside from this USB thing, pretty much everything I need works and I'm afraid I might break something worse than what I am now. But I'll look into XhciDxe.

 

What's the best way to convert from Chamelon/Chimera to Clover if I may ask?

 

thx again
