USB DVD-ROM not being mounted

[TheFu]

I too like things to work without tinkering around, but in this case I will also not learn anything about Linux if I just discard the current hardware to replace it with one that might or might not work (I have no guarantee that that drive will work on my OS-arch combination).

Here I am trying to find out why it doesn't work and what it needs to be properly working. I reached a point where I think I am close to the actual issue.

I tested it on a pi4 running a debian-based distro. Don't know how much more you expect it to be "like". Hardware being non-supported can eat lots of time and always be "close to working", but never actually work.

I hope you find a solution, but it has been 2 weeks already.

I am happy to report that today I installed Ubuntu 24.04 LTS and the DVD-ROM is now working! Seems that the new kernel has the driver built-in.
See dmesg logs:
