Hey, I need a Thunderbolt (USB C) to Firewire adapter to make use of an old FW-audio-interface but I will need to know if it is Thunderbolt 2 or 3 to buy the right adapter. Is there a way to find that out on Linux? Qwant didn't deliver any helpful results...

This has a good in-depth guide: [the_eraser] How to check (via software) if my usb 3.1gen2 Type-C port supports Thunderbolt3? usb, thunderbolt asked by the_eraser on 10:58PM - 23 Nov 17 UTC
