DVD player and printer USB no longer detected with MBA M1 ?

Using the two USB-C of my MacBookAir 2020 M1, I could perfectly use my external SSD, a printer, a DVD/CD player and of course the external monitor.

Some weeks ago that stopped only for the printer (a Brother laser) and a DVD (Samsung) which are simply no longer detected (nothing in System Information under hardware). However the SSD and monitor continue to work on the ports as before.

The printer and DVD player each work perfectly with their same adapter USB-A to -C cables on another Ventura Mac, with M2 this one. I have exhausted all my known remedies : upgraded the MacBook to Ventura 13.5, put a reset to SMC and NVRAM, started once in safe mode, tried to put USB-A hubs between the USB-C ports; tried in the DVD player several disks and including blank ones to burn ; nothing will work. The DVD player powers nicely up and spins like it does elsewhere when it is recognized, only it isn't. So there should be no power issue at least. The sudden denial of detection came maybe with a recent Ventura update, I do not know which in detail.

So what can be my next steps to get my DVD and printer detected ?

-- is downgrading to Monterey a shot worth taking -- ?
