Anonymized version attached; if you need the other version let me know and i'll dm it.  

 

Other testing done last night:  I tried disabling the usb2.0 ports and had same issue, also tried disabling the usb3.0 ports and moved the key over to the 2.0 to just make sure it wasn't something funny like that.  Neither helped.  

 

Thanks for any guidance.

Can you post a screenshot from your PCI Devices and IOMMU Groups?

 

As I don't have the NICs to test with, I assume these two links would get your sorted out:
