FL1100 based Expresscard-to-USB3.0 adapter not detected

[powerN00b]

Last year I purchased this Expresscard-to-USB3.0 adapter. It works on Windows10, but not on linux, it seems Its not being detected at all, even after I enabled all hotplug options for pci and ibm extensions!
Am I only one having issues with this chip?

powerN00b,

There are lots of kernel knobs for PCI Express Port support

some of them are hidden until other options are selected.
Here the - - symbol means hidden.

You can see hidden options with the 'z' toggle and read the help to discover how to fix it. Thus

The boolean Depends on: PCI [=y] && HOTPLUG_PCI [=n] && PCIEPORTBUS [=y] must bu true. I have HOTPLUG_PCI [=n] so that's the option to enable.

the kernel can't even see it.
