I have been using this library https://github.com/libimobiledevice/libimobiledevice to read and get information from iPhone devices connected via USB
(https://github.com/libimobiledevice/libimobiledevice/blob/bfaf1a132a0d528cfe1dae8cbb4f0ecdeccaa88d/tools/ideviceinfo.c)
I was wondering if I can use ideviceinfo.c to detect another MacOS devices connected via USB.
As I understand it, libimobiledevice can connect to iOS devices (as you have done), but macOS devices aren't supported.
You can find more information on their website.
