<< Solved >> Enable C600/X79 chipset USB2 EHCI with imacpro1,1 profile

[mike0810]

I need some help: I had to switch to imacpro1,1 SMBios because my new Radeon VII was freezing all the time with MacPro6,1. I have a X9Dai with Dual Sandybridge E5-2670. USB2.0 has stopped working, they worked well in MacPro6,1 by only renaming the USBE and EUSB to EH01 and EH02 and using the USBInjectall.kext by Rehabman. The Board has two EHCI Controllers EUSB and USBE (renamed to EH01 and EH02) and the Board has also a Renesas uPD720200 on which I gave up completely. But now, even the EHCI Controllers are not working. They are shown in the System Information as USB 2.0 Bus, but not working. I tried the USBMap Method, but no Ports show up except EH01.PR31 and EH02.PR31. Any hint? I attach the Ioreg (iojones) and Screenshots of the DSDT and unpatched DSDT. Thanks!

Issue resolved: Dont use @RehabMan newest USBInjectAll.kext 0.7.1, use 0.7.0. He stripped relevant EHCI entries!!
