Bug Description
A fix up to 39-usbmuxd.rules (initially in 21.10 but not 20.04) prevents the apple touchbar from working.
The new rule takes over the iBridge chip which prevents the github roadrunner2 macbook12-
This is the only module that activates the touchbar which means eg macbook pro models without this module have no escape key.
I discovered this updating from 20.04 to 22.04 (because I generally update only with LTS updates) but no googling came up with this issue (so one of the reasons Im logging this bug is to try and get it to be googlable).
This is a known issue that was logged as a bug over 2 years ago on the libimobiledevic
Not clear why ubuntu considered usbmuxd (which apparently is something to do with talking to other apple devices from an apple device??) to take precedence over the touchbar.
