Hi.
I said in my first E-Mail that I tried the thing under Ubuntu, and that
it is already the Expresscard Slot that NixOS does not recognize. Why do
I get suggestions to try to plug in USB Hardware then, and try it under
Ubuntu?
Anyway, I tried it under Ubuntu und Arch, it worked, I diffed
/proc/config.gz, and found some differences. Here are the kernel flags
that I chose from it which now made it work (I have no idea which one it
was, but I have no time to try it out exactly, because somehow the
Kernel is only built singly-threaded, and this takes 5 hours every time):
nixpkgs.config.packageOverrides = pkgs: {
bluez = pkgs.bluez5;
stdenv = pkgs.stdenv // {
platform = pkgs.stdenv.platform // {
kernelExtraConfig = ''
HOTPLUG_PCI y
HOTPLUG_PCI_PCIE y
HOTPLUG_PCI_ACPI y
GART_IOMMU y
# PCMCIA y
PCI_REALLOC_ENABLE_AUTO y
'';
};
};
};
Regards, CSS

And while you're at it, you should probably check `lspci -k` on the
working system to see what kernel module it uses, in case it's missing
from NixOS.

What about doing quick check and running ubuntu from livecd/usb to
confirm if card still is alive?

It might be a missing driver. Ultimately is the kernel, its
drivers and modules that deal with hardware and IO. You might need
to google around and ask specifically for the given pci expess
hardware serial code and model.

When you plug something in, the kernel log should show

How can that be?
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?
The kernel does not notice the expresscard itself when I plug
it in. My usb hard disk works perfectly under the other ports.
Ah, and fun fact: When plugging in the expresscard, I can
reproducibly scramble my sound output for a second (the music
repeats for a second after I plug it in). Still, the kernel
says nothing. And no device nodes appear.

Can you be a little more specific about "does not
work"?
Nothing happens. Like, really nothing. No new hub is
shown in lsusb
(as it was under Ubuntu). Devices I plug in are not
shown. Nothing.
When you plug it in, what messages are you seeing
while running
these 2
commands in separate terminals:
journalctl -k -f
and
udevadm monitor
Nothing. No output.
