Thunderbolt 3, USB-C connectivity issues

Open kushwavez opened this issue 3 years ago • 12 comments

I only have one RX 470 eGPU with ADT-Link TB3 adapter, with that I have some connectivity issues in macOS. As far as I can see it's something has to do with the OS, or the adapter itself.

Note: Unfortunately, I don't have any other TB3 or Type-C devices to test with, so these maybe okay for others.

The issues:

  • At System Info -> Thunderbolt it says "No drivers loaded". That is cosmetic, the devices are showing up in PCI

  • If you disconnect the eGPU the notebook will freeze (high CPU usage), you need to restart

    • I really think that this is an OS issue. -> NO, it is an issue related to my ADT-Link TB3 adapter. It is not a bug.
  • After sleep hot-plug is not working with the TB3 eGPU (device not detected)

    • Workaround: Plug the TB3 in, put the notebook into sleep, wake it up. It may fail sometimes, try it again if that is the case
      • After a while, I can say that this issue is totally random. Sometimes appearing, sometimes not.
