Hello, I am troubleshooting a Thunderbolt connection from my mac to an external PCIe enclosure which houses a graphics card. My mac have trouble detecting this enclosure. When I connect the enclosure to my mac, nothing shows up in Systems Info, except the Link status on the Thunderbolt Bus which changes from 0x101 (when TB Enclosure is not connected) to 0x7 (when TB Enclosure is connected). The setup can be illustrated like this: Thunderbolt Enclosure <------> Apple Bi-Directional TB3>TB2 Adapter <-------> Apple 2m TB2 cable <--------> MacBook Pro 15" early 2011. Question 1) What does the different Link statuses mean? (Could not find much info on this) Question 2) Could there be a physical problem with my Thunderbolt port, and how can I confirm or disprove this?
