    Where in the Bios? I only do normal shutdowns. I've tried once suspend but the restart was to dark...oh well...hello stone age.

    That's my script:

    #!/bin/bash
    cd /dev/input
    sudo setfacl --modify u:michael:rw- --modify g::rw- --modify o::rw- *
    cd ~/X-Plane_10
    sudo mount -o loop /media/michael/DATA/img/xplane10.iso /media/michael/XPLANE10

    ./X-Plane-x86_64

      USB suspend is unrelated to the overall power state (like power-on, suspend, hibernate etc.) of your machine. It's usually controlled by the OS on a per-device basis. For example, you could tell the Linux kernel to power down a given USB device if it wasn't used for more than 60 seconds.
      For making such changes in a persistent manner I'd suggest using tlp. A low-level method is to write a custom udev rule. First you should make sure that USB autosuspend is indeed the problem though. You could use e.g. the PowerTop tool to temporarily toggle autosuspend for a given device.

      • You could try downgrading the kernel.

          This doesn't make sense at all. There is no bugreport at all for udev/systemd which contains the word pedal, so please show us a link. If you actually have reported that bug the the X-Plane developers then I have to ask: Why? If it is a problem with udev report it to udev. You wouldn't report a kernel bug to the Open Office developers either.

            • That's the wrong approach. You reported it to Ubuntu distribution bug tracker, where as you should have reported it to the udev (systemd) mailing list and freedesktop.org bugzilla, and provided a link to those in the Ubuntu distribution bug tracker.
              And that's old version, 204, where as you should have tested with latest, like 215, and same with the kernel to narrow down the possibility it's already fixed.
              It might be hard with binary distribution like Ubuntu, but that's the workflow of bugs, only latest code matters (to upstream)

              • It looks more like a bug in the kernel than in udev / systemd.

                  And a quite old one.

                    How to install 215 on Ubuntu 14.04? If it's not a one click install I'm out and soon away. I simply don't want to waste time anymore on such but will prefer
                    to rather boot Windows.

                      You obviously had enough time to comment extensively on every systemd thread that came around for an extended period. If you had not spent so much time complaining and instead used that time to check the problem you would have saved a lot of time, and it would have had at least some chance of improving things while your current approach has zero chance of making any difference.
