All my USB 2.0 and USB 3.0 ports are working, the problem is all the USB 3.0 ports are slow.

Thanks!
 
what is the reported speed when you click on a device in system profiler connected to the usb3 hub?
 
well, there you go. usb2 speeds. should be up to 5gb not 480mb. use a guide to manually add the usb3 functionality to the ports using dsdt.

I'm sorry looking like a lazy person. But can you point me to the guide? I've seen RehabMan's but I am stuck with the XHC thing.

I've patch DSDTs:

I also added the -uia_ignore_rmcf in boot

I've tried using IOReg the table under XHC won't detect any USB changes if I insert or remove USB devices:

Changes only shows at EH01>PR11>HP15, HP16 and HP18 and EH02>PR21>HP25

Am I doing something wrong?

Thanks for your time
