PCIe USB hub with an m.2 adaptor

Hi,

I am trying to connect a 4x USB PCIe HUB via a PCIe to m.2 adapter, but the system does not recognize any storage when I connect it.

I have followed the steps in this guide but I think it is not compatible with this model because when I modify the kernel the system does not even boot. I have also tried to connect a SSD m.2 Samsung Evo, which is not recognized either.

My level in this system is low so I would appreciate if someone could help me with this issue.

Thank you very much for your time
