It displays the following message: "Warning: no device detected"...

That's really bad. We need to know whether this issue only occurs with older
stable kernels or also in recent kernel versions. Please verify with a recent
kernel version. If I e.g. install nerolinux-4.0.0.0b-x86_64.deb in a VM running
kernel 4.13.0-19-generic then it correctly recognizes the Qemu DVD.

Can you please re-test with a more recent kernel (e.g. v4.14) ? I have had
submitted a fix for exactly this issue with Nero and believe it is gone.

Hello Johannes,
the only versions of the kernel that seem impacted are kernel 4.9.52-> 4.9.69
I saw your fix for the kernel version 4.12 and I checked it successfully with a
4.12.1 kernel
the latest version of the kernel is not affected by this bug.

Versions tested and OK: 
4.12.1 (with your patch)
4.13.1
4.14.5

I also try kernel 4.10.0-42-generic
(VirtualBox, Ubuntu), ok too

Hello Bart,
I compiled and tested version 4.13.1 directly on my laptop
Operating System: Debian GNU / Linux 7.11
everything is OK
