Since the move, my Mac Studio refuses to recognize devices attached to any external USB hub.
System Report shows the hubs, just not anything hooked to them. #headdesk
Gonna go work on something else. Maybe my bed has stopped stinking like a dead thing?

Give this a try first. Might not help, but cannot hurt.
M-series Macs don’t have a System Management Controller (SMC). The functions the SMC handled are now handled by the M chip itself. Shut down the Mac completely. Unplug all all cables including the power cable. Leave it off for 30 seconds to perform something like an SMC reset. After 30 seconds, power on the Mac, plug in the hub. If this doesn’t work you may need to reinstall the firmware, which requires either a second Mac or a trip to the Apple Store.
Best of luck 🖖🏼
