Do I need to edit DSDT or configure kext?
USB 3.0 works well, but only 1 port out of 2.
When installing sierra USB 2.0 work like USB 1.0. USB 3.0 did not work at all.
After POSTINSTALL, GenericXHC kext turned on and USB 3.0 started to work. but USB 2.0 also works as USB 1.0

I installed yosemite and there were no problems with usb 2. but usb3 didn't work. but it is not so important. Why does the same kext work differently?
