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.
