PSA: How to fix MakeMKV + external USB drives (Arch)

[Felensis]

Hey guys,

first of all I want to generally thank all the nice fellas on this board since some of your topics and replies therein lead me to the solution to my issue. I've just registered to say this and share my solution so that it may hopefully be of use for someone else. I'm using Arch from scratch so no Arch distro like Endeavour nor Manjaro or the like is in play here. I've installed the latest MakeMKV (1.18.1 at the time of writing this topic) via pacman only to learn that it tells me that it doesn't recognize any optical disc drive even though my BD drive Hitachi-LG BP55EB40 is connected via USB and at least KDE's Dolphin or Konsole can access and read from it once a disc is inserted. So how to fix this?

In my case the following solution did the trick:

1. Temporarily usage of the BD Drive via MakeMKV in your current session is possible after loading the firmware via terminal:

   Code: Select all

   sudo modprobe sg

2. To make this work even after a system reboot so that you don't have to execute step 1 after each and every reboot:
   1. Create a new config file:

      Code: Select all

      sudo nano /etc/modules-load.d/sg.conf

   2. Just add the following to your newly created sg.conf:

      Code: Select all

      sg

3. Save the file and reboot.

I'm now able to use my external USB Blu-ray drive with MakeMKV just how it used to be.
