It just keeps going without exiting/restarting it seems. Same process ID every attempt in the log, no line about it trying to restart.
Actually calling the reset script does not help getting the device back either. Maybe it’s related to the restarting of the LTE modem when there’s no connection. (because that also uses USB)
I’ve also seen the case where the USB device still exists, but still has an error communicating.

I might just update the radio_init.sh script with a usbreset. (you can find the source online easily).
#!/bin/sh
reset either the USB hub or just the device.
if [ ! -e /dev/ttyACM0 ]; then
/usr/bin/usbreset $(lsusb -d 05e3:0608 | sed -En ‘s@^Bus ([0-9]{3}) Device ([0-9]{3}).@/dev/bus/usb/\1/\2@p’)
else
/usr/bin/usbreset $(lsusb -d 0483:5740 | sed -En 's@^Bus ([0-9]{3}) Device ([0-9]{3}).@/dev/bus/usb/\1/\2@p’)
fi
/bin/sleep 1
/usr/bin/reset_lgw.sh start 11
exit 0
Oh, it seems like the updated radio_init gets the pin from einfo and it was a different pin.
(Only found this out after uhubctl reset didn’t work either.)
