Actually you should look for PNP0200. Can have different names on different mobos.Thank you for testing this, and for doing it correctly!
I would indeed be curious to know whether the Ethernet ports are able to connect.
If you open the System DSDT (which should open automatically just by launching MaciASL), is there a device called “DMAC”?
Your DSDT does not have PNP0200 or DMAC. If Ethernet port can connect -- and we know WiFi is okay -- then it may be your 2667MHz memory or Z370 chipset.
I believe it's only for Thunderbolt and PCIe. USB uses a different communication protocol that does not required DMA which, from the entire line up of externally attached devices, only Thunderbolt or direct PCIe devices can offer.
No problems ever without VT-d with USB AI’s (Roland, Focusrite…) and my hacks.
However, with the Designare, no DMAC or PNP0200 (so no Apple DMA device) could be found in IORegistryExplorer unless you add an SSDT for it. Even if you enable VT-d correctly. I think someone mentioned it prior into the thread.
What is a PNP0200? Is that something I should have or be injecting somehow or just a limitation of my board?Your DSDT does not have PNP0200 or DMAC. If Ethernet port can connect -- and we know WiFi is okay -- then it may be your 2667MHz memory or Z370 chipset.
Do you have faster memory and more than 16GB of it?
