B_ogbrush Posted November 5, 2015 Share Posted November 5, 2015 Got Yosemite to run OK on this board.......allmost. This board has an ASMedia USB 3.0 controller. After the initial installation the machine would freeze every couple of minutes with the mouse pointer still working (but nothing else) and then re-boot after a further five minutes. In the end I found that if I disabled the ASMedia controller in the BIOS the machine woud remain stable. My Spec: Asus P8Z68-V/Gen3 (with modded BIOS)Intel Core i7 2600K 3.4Ghz12Gb RAM (1x8Gb 1x4Gb)Gigabyte GeForce GTX550TI250Gb Crucial SSD I'm booting with Chimera Does anyone have this board running with Yosemite and USB 3.0? or does anyone know of a workaround?

Riley Freeman Posted November 5, 2015 Share Posted November 5, 2015 I use the Oyen Digital driver on mine. Found GenericUSBXHCI to be a bit flaky in Yosemite. The Oyen driver is for storage only so it'll give you working USB3 hard drives and sticks but won't charge phones etc. The Oyen card uses a NEC chipset so to get it to work with the ASM1042 open the kext's info.plist and delete both instances of IOPCIMatch. 3 Link to comment Share on other sites More sharing options...
B_ogbrush Posted November 5, 2015 Author Share Posted November 5, 2015 open the kext's info.plist and delete both instances of IOPCIMatch. Thanks for the reply, please remind me how to do the above Link to comment Share on other sites More sharing options...
Riley Freeman Posted November 5, 2015 Share Posted November 5, 2015 Easiest way is to get PlistEdit Pro and use that to open the info.plist (right click the kext and show contents to get to the info.plist inside the Contents folder). Look through the info.plist and you'll see two entries that say IOPCIMatch. Delete both of these and save the plist. Now it'll load for the ASM1042.

flmmkr Posted April 20, 2017 Share Posted April 20, 2017 I tried this mXHCD.kext and am also able to get those ports working on my P79X79-E WS board finally. However, it disables my Inateck USB 3 cards that I have installed, which use the Fresco chipset and work natively OOB in Sierra. How can I get this mXHCD.kext to work with the ASM1042 ports while not disabling all the other USB 3 ports I have? Thanks! Link to comment Share on other sites More sharing options...
Riley Freeman Posted April 20, 2017 Share Posted April 20, 2017 You should be able to do this by editing the info.plist in the kext. Instead of deleting the IOPCIMatch entries, change them from 0x01941033 to 0x1b211042 (to match the ASM1042). This way it won't load for the Inateck card. 1 Link to comment Share on other sites More sharing options...
flmmkr Posted May 5, 2017 Share Posted May 5, 2017 Hey Riley, I tried changing the entries but couldn't get any USB3 ports to work at all when I did that. Link to comment Share on other sites More sharing options...
Riley Freeman Posted May 6, 2017 Share Posted May 6, 2017 Hmm, I thought that would work. I disabled the Asmedia controllers on my X79 when I got a compatible USB3 card. Link to comment Share on other sites More sharing options...

Thx ! I used this Oyen Digital Driver on my Acer 4830T and now the one lonely USB3 port works. On one USB flash drive I got 37MB/s write & 95MB/s read speeds. The USB port is NEC (0x01941033) It does not matter that the port is not listed in System Information App but it works which is the main feature.

toto1234 Posted August 27, 2017 Share Posted August 27, 2017 GenericUSBXHCI has the problem of no seeing devices you plug after boot (before boot is fine as long as you do not unplug). The workaround I found was to plug a USB3 switch. This way plugging/unplugging works all the time. Link to comment Share on other sites More sharing options...

Riley said everything correctly, just in the kext you need to swap the Device ID and Vendor ID: so, not 0x1b211042, but 0x10421b21 - first the Device ID, and then the Vendor. And everything will work) Link to comment Share on other sites More sharing options...
