mounting/using old external DVD player

[JamButty]

My desktop DVD/CD player developed delirium tremens and would not stop opening and closing so I had to just unplugit from the board.
Which led me to an old external player, a Samsung SE-208, I still have. When the system would not recognize it I went looking for answers but the little material I found is 13-15 years old so I am hoping something more current is known out there. One of those ancient refs suggested determining how the system sees it via

lsusb
dmesg | tail
ls /dev/sr*

then mounting with proper dev e.g.

udisks --mount /dev/sr0

but udisks command is not found and DMESG gives
"dmesg: read kernel buffer failed: Operation not permitted"

here full output I got from those first three

Use sudo dmesg to read those messages. See if the output of df includes the device automamtically mounted.

udisksctl is the program to request a mount from udisksd, either passing the -p option and an dbus object-path for the drive or the -b option and the name of the block-device-file.
