First up, thanks so much Rehabman for all of your work. I am blown away by all the time and effort that has gone into this topic alone.
I have made my way through 181 pages of this stuff and have gone from no usb ports to having most working. I have learnt so much. Thanks!
I have been on Mac Pro 6,1 for ages and going fine and but after updating to 10.11.6 i've had to change to iMac 14,2 to get it working and lost all my usb as a result. It has been a complete disaster that I have spent many days trying to fix.
Things are now much better but still not 100%
Some ports still don't work. My mouse seems to go dead and then need to be plugged in again to work. I have just got USB3 working on 2 of my ports which is lovely and has never happened before but it doesn't register in my system information.
I have used your InjectAllUsb thingo, i've renamed my EH01 and EH02, Ive changed to XHC (but i've still got XHC2),
and got the SSDT-XOSI going (i think) which seems to have fixed most things.
I am in WAY over my head here and i would love you to take a look at my system and see what is going on. After this much time it would be great to have it working properly.
I'm hanging on to this hackintosh system for dear life and if it wasn't for your help I don't know where I'd be.
Thanks in advance.
