Hi there,
The USB3.0 ports should be backwards compatible so can be used for USB 2.0 devices.
That said, you may have issues, as you are with the GSATA ports, because of the fact that you are running Mac OS and the necessary drivers might be missing.
If you haven't already done so visit this site:
http://www.tonymacx86.com/ which has a lot of information about running a Hackintosh and users over there might be able to offer you more help if the problem is software related, which I suspect it is, as everything worked when you were running Windows 7.
