Mac Mini M4 16GB Just updated to Tahoe from Sequoia and I have a USB hub (TB cable to standard brand USB 4 socket hub) plugged into the TB rear port but now not working on any of the rear TB ports but works on the front USB-C ports, is this something that Tahoe changed?... Thanks if anyone can help !
Got a tip for us?

No, but try disconnecting and reconnecting it. When you say "its not working" can you clarify? Are you getting power, any errors?
Tried that first up and lots of re-starts etc, the hub is https://www.amazon.co.uk/dp/B01DYD3Q28?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1 and was fine off the back TB USB port on the mini but re-boot after update to Tahoe and not working on all TB ports but OK on the front USB-C ports. I dont have any USB-C type connector devices to try the ports with one item but have orderded some little USB-C to standard USB adapters to see if its the hub not compatible with Tahoe.... boy do I wish I had not of clicked the update message !

FIX........unplugged the devices attached to the hub one at a time and unplugging a USB switch box I had off the hub made it work again, was able to re-plug the switch box and carried on working ok ... so I guess something random with the USB switch box
