means ....but they already working before the name change.

It is likely the SMBIOS you're using does not have a built-in port injector. Or the built-in port injector just happened to be compatible with your USB topology.

There is a MacBookPro8,1 EHCI port injector. See Info.plist in AppleUSBEHCIPCI.kext for more details...

No idea what you mean. It is unlikely the built-in port injector is a perfect match for your USB topology.

It is because you're running in the port limit (15).

Since you're using USBInjectAll and FakePCIID_XHCIMux, you can use the "-uia_exclude_hs" kernel flag to eliminate all HSxx ports from XHC, which will bring you back under the 15 port limit.

Kernel flags are specified in config.plist/Boot/Arguments.

Thanks it worked!!! The only thing doesn't work now is a usb midi controller, it has USB1 and when i plug it at any of the back port it doesn't get recognized, thanks god it's working on one of the front usb ports...

i think that the back USB 2.1/1.1 ports don't work as 1.1 (as it mentioned in the mobo specs) so the machine doesn't get recognized...is it possible?

Thanks in advance!
