@ofborg Could you explain me how to apply these changes on my NixOS version 21.11 for check moxa uport converter with this driver

[arkivm]

@uralbash could you try applying this patch if you have a local checkout and do
nix-build -KA linuxKernel.packages.linux_x_y.mxu11x0 (replace x_y with your version)? The modules should be in your ./result/lib/path/to/mod/mxu...ko. If you are not on a nixos supported kernel, you can build your own or override the versions as mentioned in this wiki.
Unfortunately, I don't have a hardware to test.

I checked MOXA UPort 1130 equipment in mode RS-485 on NixOS 21.11 with 5.10.81 Linux Kernel. The essence of the experiment to transfer data through RS-485 line. Technique was to connect two converters (UPort 1130) among themselves and get the echo signal.

PC (NixOS) - USB0 <-----UPort1130 
          |               |A   | B
          |               |    |
          |               |A   | B
           \ - USB1 <------UPort1130 

I can confirm that it works on real equipment

@uralbash: Great. Thank you for testing it on real hw
