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

https://raw.githubusercontent.com/RehabMan/OS-X-USB-Inject-All/master/config_patches.plist

 

Notes: 

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
