I'd delete this post, but it's telling me I don't have deletion rights. Turns out I forgot I swapped drives when I built my new PC and put my old PSX-era burner in the external caddy. Inserting a disc into THE CORRECT DRIVE shows the contents as expected.
Feel free to delete!

Last was Intel, this one AMD. Drive is in an external enclosure and has ripped many a UHD.
This was my first time trying to rip a disc on my new PC. I wanted to rip Joker and updated to 1.15.1 before inserting the disc. It couldn't read the disc. I inserted a known working, and previously ripped UHD disc. Nothing. I inserted a Blu-ray that had previously been ripped. Nothing.
I downgraded to 1.14.7. Nothing. I then thought perhaps I should take the plunge and finally install a Libredrive firmware, as MakeMKV was now telling me my drive was compatible with a firmware flash.
Flash said it was successful. Nothing.
I then dug out an old USB 2.0 hub in case this new system's USB 3.1 ports were the problem. Nothing.
I have power cycled the drive countless times.
I humbly present the following debug report--this is all it provides. Help please!
