Our firm has just upgraded our AV machine to an AMD Threadripper 2 2950X/Gigabyte X399 from an older Intel 5960X/Asus x99. Huge (and greatly appreciated) speed boost in everything we do, but can no longer connect a 5D Mk IV via USB connection. Software environment is a fresh install of Win10 Pro x64, v1809.
Attempted troubleshooting steps:
This problem appears localised to the new Ryzen-based production environment, as the EOS3 utility and camera are able to sucessfully connect via USB on the older Haswell-E Intel machine and, as a test, on a new-out-of-box Surface Pro 4.
Any further suggestions or troubleshooting steps to attempt would be greatly appreciated, as we shoot purely in large-format RAW and so the file transfer times via wifi are cripplingly slow and seriously frustrating.

I just updated the bios of my Aorus x570 ultra to F33i which should be dealing with known USB issues, but the problem remains exactly the same as before. Really frustrating that a 4K camera and a 3K PC are simply unable to even transfer an image to one another. Was that a 1000$ extra option for each of the devices?
The firmware update didn't fix it probably because the AMD chipset seems to have a hardware related issue when it comes to their USB ports. This has been an ongoing problem for a number of years. It should not take years to update firmware to fix any type of firmware related issue, and it doesn't.
Thanks all for your contributions - confirming 1.3.3 has also solved this problem for us.
Extremely annoying that it's taken the best part of three years for this to be resolved, with still no actual communication from Canon, but glad we're at the end of the road.
Firmware 1.3.3 does not solve this issue. I have an ASUS Zenith Extreme Alpha X399 board with a Threadripper 2950x and my 5D Mark IV is running firmware 1.3.3 and I am still unable to use EOS Utility 3 when connected to a USB 3.1 port (the application just hangs on the splash screen, just like it's always done). Connecting to a USB 2.0 port works fine. This still needs to be resolved.
I agree. The new firmware fixed it on my Ryzen Lenovo laptop, but on my desktop PC (despite all the latest drivers and mobo firmware) I have the same USB3 issues connecting the Canon MKIV to any USB3 or 3.1 ports. Frustrating that the Canon 5d mkIV works perfectly on USB3 with my 10 yearold intel-powered desktop. While there is a fix that has helped many, there appears to be gaps in the solution.
The off the shelf AMD machines seem to work with the firmware update. It seems like the issue seems to occur most often with home brewed AMD platforms.
