PinePhone modem keeps "disappearing"

[zetabeta]

I tryed a workaround for modem disappearing, maybe too soon, is only about a couple of hours and about 10 wake up process, but modem never disappeared, my workaround is:
AT+QCFG="usbnet",1
this command change type of usb
0 = PPP & QMI (default)
1= ECM
2=MBIM
3=RNDIS (only for windows, but it can work also for linux)
changing to 1, ECM, seems it fix

P.S. Do you know how send AT commands?
for example
mmcli -m any --command='AT+QCFG="usbnet",1'
for some people mmcli command can fail, there is something to do earlier if it fail, but i forgot

i documentated for giving mmcli command if they fail:
give these two commands

sudo service ModemManager stop
sudo /usr/sbin/ModemManager --debug

now on second shell you can give your mmcli command

after

on first sheet CTRL+C
sudo service ModemManager start

i think you are going to be disappointed.
