I am trying to migrate my data from my old MacBook (12-inch Retina Mid 2017) to a new Apple MacBook Air (Retina, 13-inch, 2020). I am using the USB port on an Apple AV Adapter on the MB connected using this Amazon cable and the drive never shows up when using Apple Migration Assistant on the new MBA.
I have reseated the cables multiple times and used multiple Apple and non Apple adapters and it doesnt work. Has anyone successfully completed this migration using USB cables and if so, what cables did you use?
I'd love to use the Apple Thunderbolt yet the MB only has one port and it's USB-C, so I need an adapter for power during the transfer.
Thanks for any assistance.

The problem is your cable
Emphasis mine
You need a proper USB cable, not a charger cable. A charger cable only provides the connections to send power, not data.
A USB cable for data will typicaly not need a descriptor (like "data") because it's assumed USB cables carry data. However, Amazon sellers may describe it as "sync" in their products title.
