Bug description

I am using a Radxa Rock 5B as a small home router (and soon as a nas). It dials up using USB tethering from an iPhone. Every few hour it lost the IP on the tethered interface and set a link-local one.

Steps to reproduce

Using a iPhone for USB-Tethering and waiting a while.

Screenshots

No response

Additional context

I suspect it is caused by linux' tendencies to sleep USB devices after a while of no use, thus I created the following udev rules (sudo nano /etc/udev/rules.d/50-iphone-tethering.rules):

# iPhone USB Tethering - Disable autosuspend
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="05ac", ATTR{idProduct}=="12a[0-9a-f]", ATTR{power/control}="on"

# Also set Parent-Device (Hub) to "on"
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="05ac", ATTRS{idProduct}=="12a[0-9a-f]", RUN+="/bin/sh -c 'echo on > /sys$DEVPATH/../power/control'"

Additionally I disallowed setting a link-local IP for the iPhones eth1 interface setting noipv4ll in dhcpcd.conf.

Relevant log output

Not yet captured since the behaviour cannot be triggered at will but occurs after multiple hours and this is the first time I took action.
