/dev/sr0 (live DVD) turns into /dev/sr1 when inserting periphials

On a live Linux session, inserting a keyboard or mouse via USB onto the computer causes /dev/sr0 to be remapped as /dev/sr1, which makes the live system unable to access the DVD.
sudo rename /dev/sr1 /dev/sr0 does rename the device file but running lsblk still shows the DVD drive as sr1.
Additionally, sudo mount /dev/sr1 /cdrom -o noatime` (default mounting options) do not fix the Input/Output errors from loop0, which represents the SquashFS.
Even after that, I still get an Input/Output errors and SquashFS errors, because SquashFS memorizes unreadable sectors, which causes them even to be inaccessible, despite the DVD is mounted correctly and available again.
How can I make SquashFS read from the DVD again and reset the errors?

Which live system (distribution, version)? Is the DVD a USB peripheral? It would help to post the kernel logs (all the kernel logs starting when you insert the USB peripheral that messes up the DVD access). Post logs from a session where you don't try to rename the device file, because that can't help but could add problems of its own.

@Gilles It is Ubuntu Studio 16.04.2 LTS, and the DVD is internal, but it also happens on a different laptop where the DVD drive is an external one with USB. I will post the kernel logs the next time it happens.
