USB3 drives not mounting and/or copying files with ASM1042. Caldigit kexts...

From my post on insanelymac:

I have an Asus P9X79-E WS with Asmedia ASM1042 chipset. I have some drives that will show up, but copying files to or from any drive yields an Error -36 message. Some other drives don't show at all. I tried adding the DisableUAS string and false key under the IOKitPersonalities/GenericXHCI section of the Info.plist in GenericUSBXHCI.kext 1.2.7, but that didn't work.

I also tried changing the IOProbeScore value to -1, but that didn't work either.

The same drives all work with the USB2 ports with no issues.

I tried editing /System/Library/Extensions/AppleKextExcludeList.kext/Contents/Info.plist and confirmed the kext is loading.

I also found that the drive that won't mount in the USB3 port, will mount if it's connected at boot up. If I connect it after the OS is already loaded it won't mount and won't appear in Disk Utility at all.

Lastly, I tried the CalDigit kexts and they got the USB3 ports working with some drives, but not others. I have an HGST Touro Portable USB3 drive that is working, and I have a Seagate GoFlex Portable USB3 drive that still does work at all. It won't mount and doesn't show in Disk Utility at all. It does work on the USB2 ports and works on the USB3 ports on my MacBook Pro.

I posted running, caps, and bdmesg xhcdumps on the GenericSUBXHCI thread on insanelymac here: http://www.insanelymac.com/forum/topic/286860-genericusbxhci-usb-30-driver-for-os-x-with-source/?p=1993011 I'm also attaching them to this ticket. I had the Touro portable drive connected to one port on the back and the Seagate GoFlex portable connected to a port on the front.
