You can do a couple of things. First, the mackyreddy ML image is based on i7-2630QM, so make sure you are using the correct DSDT and SSDTs. Second, make sure you are using A19 custom bios, also reset the bios to default. From what I can see you might have USB Legacy turned on.
I'm still a little bit confused about the BIOS and DSDT. I have the modded OSX A19 BIOS. But I'm using DSDT which was provided by mackyreddy as I don't know how to patch the DSDTs yet
Also, I'm confused about how many partitions will I need for Clover. This is why direction will come handy
