2tbt3-pcie-enclosure won't works. Thunderbolt device functionality might be limited

Hello. I have a problem with my new 2TBT3-PCIE-ENCLOSURE. Every time I try to connect it to my Dell G15 5530 the same problem occurs. “Thunderbolt device functionality might be limited”. I can see it in Device manager > USB devices >…
But that is all…
Checked all the drivers. All up to date. Tried all the cables including the one that comes with device. Nothing works

Hello @Vitaly and thank you for your interest in our Community.

From your description, it seems like our Thunderbolt chassis may be connected to a non-Thunderbolt computer (or port).

Would it be possible to please confirm the brand and model of your laptop, as well as which port are you using to connect the chassis to? In order to work, this Thunderbolt chassis needs to be connected to a Thunderbolt 3 port (on a Thunderbolt 3 capable computer) and specifically use a Thunderbolt 3 cable (our provided cable will have a thunderbolt symbol on it).

I look forward to hearing back from you!
