Disabling Unrestricted FS (SIP) causes USB ports to not work

[cnrd]

Hi

I have been battling this bug for a very very long time now and would like to know if anyone have any ideas on what I can try to fix it.

First of all, I'm using USBInjectAll with an SSDT to inject only the ports I use (15<), I have attached a copy of my SSDT in case there is anything in there. I have also tested just using the raise limit patch and a modified version of the USB SSDT found in the BIOS, but this did not change anything.
This is running on a GZ-Z170X-UD3.

As long as I have the SIP flag Unrestricted FS enabled all my USB work correctly.

If I disable Unrestricted FS then all my USB ports stop working, except the USB 3.1 (USB C with an Apple USB C to A adapter). That is all USB ports on the USB 3.0 controller stops working, both USB 2.0 and 3.0 headers/ports.

I can still control the system through Remote Desktop, and if I plug a keyboard in the USB C to A adapter, then I can also use that.

I can disable all SIP flags except Unrestricted FS, but I have no idea about why that flag would cause problems with USB ports.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Here are two logs, one where Unrestricted FS is not disabled (debug_working.zip) and one where Unrestricted FS is disabled (debug_not_working.zip).

Hmm... no idea. According to ioreg, USBInjectAll.kext is still doing its normal thing...

I always use CsrActiveConfig=0x67 (don't see much point in enabling SIP), and I haven't done any experimentation with VirtualSMC.efi+VirtualSMC.kext as FakeSMC.kext replacement.

You might consider installing all your kexts to /L/E. Be careful with rebuilding cache only when SIP is disabled though.

Yeah that is also why it's so puzzling to me, everything seems to be correct.

I also had the same problem with FakeSMC.kext + SMCHelper.efi

I'm pretty sure the problem has existed all the way through High Sierra, so I may just have to give up and run with 0x67 instead.

Also I have no idea bout why not allowing writes to some parts of the file system should touch USB in any way. (Which I'm pretty sure is what Unrestricted FS does?)
