That new log doesn’t look any different.
It basically contains the same lines like the original poster had.
Have you checked the first reply which links to FP3+ no USB conection via fastboot, unlocking bootloader not possible
Right now I can imagine 3 reasons why the log looks the way it does
- it’s not a data cable
- the phone is not in USB debugging mode
- windows lacks some driver to use USB debugging mode
The latter might be helped with above link.
