I bought a usb c hub for my macbook pro 2022. All say it should work but it

Yes, you can use any USB-C plug on your MacBook Pro 2022.

Typically, that plug may be snug fitting, so line it up and push it in until you feel or hear it click into place.

Are you having some other, more specific problem with the hub?

You're welcome.

As Yoda might say "Do or do not. There is no 'try'".

"Being in most of the way..." really does not guarantee that a device will talk with other devices.
