Sierra usbs not working on laptop acer v7 582pg

Hi everybody!

After installing Sierra zone usbs, webcam, and microphone are not working. ( wifi and intel 4400 either but that is less urgent ).

Laptop hardware works almost out of the box on Yosemite Zone ( Unfortunatelly Xcode is a requirement ).

Everytime I save clover configurator plist, even if I don't change anything, I get a system up time and doesn't boot anymore.

Any help will be greatlty appreciated.


More info:

Laptop hardware is i54200u, gtx750m. Bios locked.

For installation I boot from usb2.0 port with flags -x -v maxmem=4096 dart=0
it shows "waiting root device" message until I remove the usb device from the 2.0port and plug it into the 3.0 port and installation automatically resumes.
I guess something is wrong with the usbs right from the start.

With USBInjectAll kext 

Try to apply the correct Clover Config patch with the following file




If you have an X99-series chipset XHC controller, 8086:8d31, install XHCI-x99-injector.kext from the project as well. The USB3 drivers will not load without this injector kext.

If you have a 200-series chipset XHC controller, 8086:a2af, you may need to install XHCI-200-series-injector.kext from the project. The drivers will load without it, but maybe not the correct ones. This injector kext invokes the same drivers used by 100-series 8086:a12f.


Here you can find those kexts if you need
