Hi,


  > The proper way to do this is to set up modaliases

  Could you please elaborate further?


the alias in the line below depends on the exact PID and VID of your device so 
you may need to adjust it:

 boot.kernelModules = [ "rt2800usb" ];
 boot.extraModprobeConfig = ''
   alias usb:v0B05p17E8d*dc*dsc*dp*ic*isc*ip*in* rt2800usb
   install rt2800usb ${pkgs.kmod}/sbin/modprobe --ignore-install rt2800usb && echo 
0x0B05 0x17E8 >/sys/bus/usb/drivers/rt2800usb/new_id
 '';

Hi,


I would have gone to systemd.services. Slightly uglier looking (bigger
attrset), but should run after the kernel has loaded its modules. I'd
say it would be ideal to have it be "PartOf = networking.target"
and/or "Before = dhcpd.service" (or whatever networking thingy you
use).


Actually, that will not do the trick either if the device isn't plugged
in yet.

The proper way to do this is to set up modaliases

[Strahinja Popovic]

Thanks for help Peter,

But I have in dmesg now:

[2.027361] stage-2-init:
/nix/store/zv42ylc0jangv5kv437577qq79v3xq5n-nixos-system-strale-17.03.1033.99dfb6dce3/activate:
line 136: /sys/bus/usb/drivers/rt2800usb/new_id: No such file or directory

How to make it to wait for kernel module?

[Peter Hoeg]

Hi,


  I have made my USB WiFi to work,
  but I have to call this script whenever I restart the computer.


you can do it this way:

system.activationScripts = {
 rt2800usb = {
   text = ''
 echo "0b05 17e8" > /sys/bus/usb/drivers/rt2800usb/new_id
   '';
   deps = [];
 };
};

[Nix-dev] [NixOS] How to incorporate my Bash script in configuration.nix?

[Strahinja Popovic]

Hi everyone,

I have made my USB WiFi to work,
but I have to call this script whenever I restart the computer.

#!/usr/bin/env bash
echo "0b05 17e8"|sudo tee /sys/bus/usb/drivers/rt2800usb/new_id

What is correct way to make this part of configuration.nix?

Cheers,
