Mac Studio (OS Sequoia) not recognising SuperDrive

My old SuperDrive, which up until recently has been working reliably for years, has suddenly stopped accepting discs on my Mac Studio running Sequoia. It was fine until I updated the OS. It was plugged into USB-C with a USB to USB-C adapter, and has worked perfectly everytime for 12 months.

Just in case it was the adapter, I plugged it into the USB port on the rear and it worked for a day or so, then suddenly stopped accepting discs again.

So I booted up my old iMac (Late 2012) running Catalina. This is the Mac I've been using the SuperDrive on since 2012, and it never skipped a beat. And lo and behold, it worked first go, just like it always has.

I immediately plugged the SuperDrive back into the Studio Mac, and again, nothing.

Is it possible the latest OS isn't as compatible with the old SuperDrive? Has anyone else had this issue?
