Hi and welcome,
Never seen this done or tried it. Seems like a interesting project 
Support for thunderbolt is in the kernel, so this might be an issue with the detection, arch wiki states: Modern Thunderbolt devices implement security modes that require user authorization when connecting devices
Further reading: Thunderbolt - ArchWiki
Maybe add some more info about the hardware detection. Terminal output from the livecd
inxi -v7azy
should provide enough initial detail for users to get a good idea what is happening on your side.
