Yes, this is my understanding too.
Your inputs and USB backward compatability led to the solution of my problem.
If backward USB comparability didn't exist I would then need an adapter or new mixer, but my existing [old USB2] mixer works fine with my [new USB3.2] laptop.
This is what my AI assistant says on the subject:

"Yes, USB is designed to be backward compatible across generations. That means your USB 2.0 mixer should work just fine when plugged into a USB 3.2 port on your laptop."

ROG, thanks again for clearly seeing this and sharing your knowledge.

For me there’s no better place in the band than to have one leg in the harmony world and the other in the percussive. Thank you Paul Tutmarc and Leo Fender.
