Here is what I’ve concluded regarding the Asmedia USB 3.0 problem.
The NEC/Rensas USB 3.0 driver that is included in MultiBeast is causing the “shutdown” problem on the SH67H3/7.
So, we still need an Asmedia USB 3.0 driver for Mac, for all to work perfectly.
Right now, here are your choices:
1) Working USB 3.0 ports, with a shutdown problem
2) Don’t install the NEC/Renasas driver, no USB 3.0 ports working, but hackintosh shuts down properly
As I’ve stated before, I have access to the source code for the Linux Asmedia USB 3.0 driver, but need someone to convert it to Mac. If anyone has the ability to do this, please let us know, so we can all experience some JOY here.

Interesting bits of info on the Shuttle SH67H3/7! I am strongly considering this system myself for OS X Lion.
How did you fare with the audio, btw.? I’ve read reports of background noise and other issues with the ALC888, which the SH67 uses.
Also, have you tried modifying the DSDT in order to get shutdown working with the ASMedia USB 3.0 drivers?
Audio – I didn’t use the Realtek Audio driver, due to the background noise. I used the VoodooHDA driver which works just fine.
Shutdown Problem – There is no Asmedia USB 3.0 driver available. In MultiBeast there is a Renesas/NEC USB 3.0 driver, which is the one causing the shutdown problem. I have not tried editing the DSDT of the Renesas driver to fix the shutdown issue. If you do intend to build and install Mac Lion, there is a firmware update you must install along with the Rensas/NEC driver for the ports to work. I have posted a link to the firmware update.
Thanks for the quick reply! Good to hear that the VoodooHDA driver works. Is it the 2.7.3 version you’re using, and with/without the AppleHDA rollback?
Personally I am using VoodooHDA myself–although it’s an older version (0.2.1)–on both my laptop OS X Lion install (Fujitsu-Siemens Lifebook E8410) and a stationary (Dell Dimension 9200). It has worked pretty well.
I am unsure if I am going to use the Reneas driver (which it indeed is called; I don’t really use MultiBeast all that much
, as it apparently requires the firmware to be flashed from within W*ndows (which I do not use anywhere).
I’m going to try the ports from Linux and do some firmware checking first. USB3 support came pretty early in the 2.6 kernel, so surely there must be a way to get it working from within OS X or another *nix. As for native OS X support I guess it depends on which chipset Apple eventually chooses.
The non-shutdown thing bothers me more than having USB3, frankly. I have this problem on the laptop (in addition to not being able to use the internal LVDS display), and it is quite cumbersome to force the power off every time. Help around various forums seems to be scarce, unfortunately, regarding DSDT editing and such.
btw., my choice stood between this SH67H7 Shuttle model and the recently-announced SZ68R5. However, from reading various user experiences of Intel’s Z68 (especially on tonymacx86.com) it seems that particular chipset perhaps wasn’t the best alternative currently.
I used the VoodooHDA 2.7.2 and I believe I did the AppleHDA rollBack also.
Keep us posted on what you find.
