[Nix-dev] PCI Expresscard not working under NixOS

[Roger Qiu]

When you plug something in, the kernel log should show something. If it
doesn't then the kernel doesn't know about it, nothing in the userspace can
help.

Make sure you're running those commands before you plug the usb in.

Also I used to have faulty usb cables, but even then the kernel showed
something. Usually repeating messages because the usb cable kept dropping
out and coming back in.

What happens if you plug those devices directly?
