My iPad running MIRA connects to my MacBook Pro M3 on the Thunderbolt 4 port but it only receives power on the USB3 port of my Satechi Type-C Multi-Port Adapter 4K and does not communicate with MAX.

It will communicate with MAX when I use USB-C to USB-A on the Satechi Type-C Multi-Port Adapter.

I'm trying to get my head around all the ports, the USB-C vs Thunderbolt communication on the new Macs because I want to use a USB-C adapter for my iPad MIRA to my Laptop communication.
