Unable to connect device after every kernel update

[cooperbang]

After every Kernel Update my iPhone 7 is not recognized by usbmuxd.

After replugging the device I get:

Workaround: sudo killall -9 usbmuxd and then systemctl start usbmuxd - after some time it will connect...

Connect successfull after stop/start usbmuxd:

FYI I have the same issue, whatever the kernel I have to kill usbmuxd and restart it

To solve this, I compile my own kernel with : CONFIG_APPLE_MFI_FASTCHARGE=y

in : Device Drivers / USB Support / Fast charge control for iOS devices

In case: We discussed about this issue on LQ forum https://www.linuxquestions.org/questions/slackware-14/tethering-iphone-kernel-modules-4175699876/
