Am I correct in assuming that the USB cable can be plugged into a Thunderbolt port with an adaptor?
The documentation assumes it is a USB cable with Type C connectors, but I see no reason why a type A to type C adaptor would not work other than the adapter might not be 100% compliant with the standards.
And if so, why must it be USB?
Because...
- ...the manual emphatically specifies USB and explicitely states Thunderbolt 3 cables will not work? (Had I known this previously, I would have had better success using Apple Configurator 2 when I managed to entirely erase the boot drive on an M1 Mac mini, but I was using instructions from a third party that were not as thorough as the AC2 User Manual.)
- ...USB is implemented entirely in hardware.
- ...Firewire is at least one protocol layer above USB and requires firmware to function.
- ...One of the primary functions of Apple Configurator 2 is to update/revise/refresh the firmware
- ...the firmware cannot be updated/refreshed/revived while it is in use
And have you any idea why it must be a USB cable?
PLAUSABLE DENIABILITY: the following is somewhere between fuzzy speculation and a wild-a**-guess. I would have to dig a lot deeper into the hardware standards and implementation to do any better.
- USB is implemented entirely in hardware.
- There is a level of intelligence in the Thunderbolt connector
- Firewire is at least one protocol layer above USB and requires firmware to function.
