Not quite expensive but that is me. First MBP in five years and both USB C travel hubs I use (each around $100) no longer work at all in my 16 in M1 Max but oddly continue to work on my 2016 MBP which I upgraded to Monterey for the machine migration and used both hubs with no issue on my Monterey 2016 MBP during a phone call with Apple support yesterday.
Reading a few articles made me think this might possibly be an M1 issue:
If you are thinking of buying a M1 powered Mac and rely on fast, external, storage via a USB-C interface, you may want to reconsider. The Thunderbolt/USB-C ports on M1 Macs don’t work. They work to some degree, they just don’t work properly; they don’t allow attachment of many external USB-C...

The interesting thing is my hubs can be seen in System Information from the About This Mac screen on the M1. That is why I am hoping this is a software situation.
Bit of irony that they say less dongles for this new Mac and I am heading on the road Monday with more dongles than ever before. I used to take two travel hubs for all of my connections (one as a backup in case the other failed) and now will need to pack Ethernet, VGA and USBA dongles which will fill all the ports when I present at a conference next week.
Really happy I use a hub in my home office setup or there would have been a really good chance I would have headed to a conference with no connection options. I am sure things could have been scrounged up but I wonder how many people who often use these hubs for presenting at conferences, meetings and whatnot might get caught by this.
Thank you for this thread. Going to contact the conference coordinators of my next two conferences to suggest they have more dongles than usual on hand.
