Is there any solution to enable USB3 on non-intel chipsets, on VIA more precisely?
In my system all USB ports can work ... but all usb port detected into the usb 3.0, including USB 2.0 .
USBEHCIPCI.kext not work for USB 2.0, all usb ports handled by USBXHCPCI.kext .
with or without usb patch get the same results .

What should I do to USBEHCIPCI.kext can work for usb 2.0 .. ?
Great guide and thanks for all of your hard work. I am trying to set it up on my GA-Z87MX-D3H - however I have some questions.
- I've never needed a DSDT before - which one should I use and modify for my board?
- My controller already seems to be name 'XHC' by default and I can see all of my USB devices (see screenshot and ioreg explorer output: View attachment 154724)

- I am not sure my USB 3.0 high speed device (IB-328U3SEb) is working correctly - despite being attached to USB 3.0 Bus in the System Profiler screen (see screenshot)

- I have a strange issue whereby my built-in camera for my cinema display "freezes" after a period of time. I suspect this may be related to USB as this was working flawlessly in Yosemite and also since the camera is hooked up via a USB port.
i there mr rehabman!!!!!Always use your own native DSDT, extracted and patched if needed.
For most desktop boards, patching DSDT is not needed as you can do most everything through config.plist or additional SSDTs. See the BRIX repo as an example.
If all your devices/ports are working as expected, then you don't need to implement any solutions here.
Your storage device shown in your photo is working at USB2 speeds. (attached to HSxx port).
Check your USB settings in BIOS.
i there mr rehabman!!!!!
currently i'm trying to fix my usb according to your guide and but the problem is how to identify my ports
(i have only 4 usb 3.0 ports only)
