Hi Laurent,
I'm really sorry for all the wrong formatting. I already took measures so it
won't happen again.

Thanks a lot. Highly appreciated.

I guess you want the verbose output of lsusb. You'll find it in the attached
file. It might contain more than than you expect as the iBridge device is a
custom ARM processor (probably very similar to the one in the Apple Watch),
not just connecting the webcam to the rest of the system, but also the Touch
Bar and the Touch ID sensor.
Regards,
Daniel
