For low-level stuff, Apple used to have a developer tool named “USB Prober” for logging USB Traffic (https://developer.apple.com/download/all/?q=IOUSB https://developer.apple.com/download/all/?q=IOUSB), but that seems to have been abandoned.
Google tells me you can use WireShark to capture packets (https://developer.apple.com/forums/thread/95380 https://developer.apple.com/forums/thread/95380) after disabling system integrity protection (https://developer.apple.com/forums/thread/124875 https://developer.apple.com/forums/thread/124875)
I wouldn’t know whether that works today. Also, it wouldn’t be “time-series coordinates”, but that information would be in the data captured.
