I also experience problems with USB on BigSure, M1 MacBook Pro 13". I have Dell D6000. I'm not sure it is USB2 only though. In my experience it is rather random. Some times it is the webcam, sometimes it is the speakers or the TimeMachine HDD on USB3.

One thing which helps is to power off the dock if you do not use it. Power on before connecting and connect the MacBook with the lid open. In this case, the chance to see all USB devices is the highest... I close to send it back...

PS. And yes, I checked the firmware. It is the latest one. For the firmware update you need a Windows PC, but not necessarily one from Dell ;-)
