Only one USB 3 port usable for USB 3 devices at USB 3 speeds.

I have multiple USB 3 ports on my computer, however, only one USB 3 port located in the front panel recognizes my USB 3 devices. If I plug any USB 2 devices into the USB 3 ports they work without a problem. However, if I take my USB 3 devices and plug them into the USB 2 ports they but at the USB 2 speed, of course.

In summary:
Only one USB 3 port works with USB 3 devices
All USB 3 ports work with USB 2 devices
All USB 2 ports work with USB 2 and 3 devices.

So I'm stuck only being able to use one USB 3 device at USB 3 speeds.

Gigabyte - GA-Z97X-UD3H ATX LGA1150 Motherboard
Corsair - Carbide 500R Black ATX Mid Tower Case

I have same setup and all ports working at full speed USB3.0

The only thing I have done is to add the USB_Series9_Injector.kext to my clover kexts folder.

Apologies if this is a dumb question, but where can I find that specific kext? And do I need to change any settings in Clover? (Pretty new to using clover)

Having the same problem here using the ga-z270n-WiFi. Tried to rerun multibeast to install the Kext needed but it won’t work

Got it, reran multibeast and selected 200 series usb drivers, restarted and all is good now
