I am running an actual 14" MacBook Pro with M1, and using a small Belkin-7-in-1-Multiport-USB-C-Hub.
No general issue with connection to my Kemper - the Belkin dock works pretty fine.
Only thing is: .... if my MacBook goes to sleep during a short break, it losts connection to the Kemper after wake-up.
But had the same issue before with a MacBook Air with USB 2.0 directly plugged in .....
