[Solved] USB 3.0 speed is the same as usb 2.0 on High Sierra

[sanigo]

I have patched dsdt following [Guide] 10.11+ USB changes and solutions. The usb ports were all worked.
But the usb 3.0 speed is too poor, 20MB ~ 40MB, it should be around 200MB.
While patching, I could not found SSxx ports, all ports are named HSxx, and the red usb port is not under XHC.

I have fixed this problem. The fixed dsdt is attached.

@chungs420b, please update your profile (personal details) with your Motherboard, CPU and iGPU or Graphics Card.
If you have a prebuilt computer enter make and model instead of motherboard (Mobo).

Profiles need to contain at least your primary system to assist others with helping you.
