Mojave 10.14.4 Port Limit Removal Patch

Only two out of seven ports were working in Linux when booted directly from the bios. I have noticed that when I shut down the computer the USB ports remain powered up. After I shut down this last time I waited about 30 seconds and I turned the switch on the power supply off and I think I noticed the lights in the room flicker and now the whole thing is dead. So no more custom Mac until I can get a new power supply and maybe a motherboard. It might be more enjoyable to get my old Z68 Sandy Bridge machine out of the closet. It ran Sierra pretty well When I took it out of service.

Yikes! Sorry to hear that. No lights on the MB?
 
Thanks!! Saved my day

No signs of life at all. I will pull the power supply of the old Sandy Bridge machine and see if I can power this sad collection of parts back up, after which I will see if I can find a PCI USB board to work with until I can teach myself to implement a SSDT. I have to say though, if I total up the hours that I’ve spent trying to keep my custom Macs running, I might really be better off just buying a proper Macintosh from Apple. Or at least not have only a custom Mac to rely on.

Naaaah. It's back up and running again. All I had to do a swap out the power supply. And now I pose my question again, would it be possible to run a USB board in the PCI slot and have USB 3 there while I am sorting out the SSDT issue for the regular back panel usb?
 
So it seems that two USB ports, one 3.0 port and one 3.1 type A port, were rendered useless when the power supply failed. When I boot the mac os they just power up but are otherwise useless. The other 3.0 and 3.1 ports, that I have labeled as working in the attached diagram, only work under Linux. Only the usb 2.0 ports work under mac os. I am still hoping to fix the ports that work under Linux for the mac os by implementing an SSDT, something I still need to learn how to do.

If I put this...

Code:
-uia_exclude=HS01,HS02,HS03,HS04,HS05,HS06,HS07,HS08,HS09,HS10,HS11,HS12,SS07,SS08,SS09,SS10

… in as a boot flag, would it be sufficient to get me under the USB port limit in the Mac OS for the purposes of conducting a test to get the remaining usb 3.0 ports to work properly?
