GSM SMS usb modem problem after update from os 4.9 to 5.x

Good morning,
after updating HA OS to version 5, the usb gsm modem has stopped sending messages with the following errors:

Failed to read signal quality: ERR_DEVICEWRITEERROR

and

Sending to xxxxxxxx failed: ERR_EMPTYSMSC

I checked via ssh that in the / dev folder, the modem was seen correctly, and it correctly sees ttyUSB0 and ttyUSB1.
for safety I reconfigured the SMS notifications integration by trying both devices (ttyUSB0 and ttyUSB1), this is the procedure I followed:

1- eliminated integration and restarted HA
2- added SMS integration and restarted HA

SMS notification services are sometimes created and sometimes not, but when present they return the errors written above.

However, I noticed via the web in the section “Supervisor-> System-> HostSystem-> Hardware” that the /dev/ttyUSBx devices change every time HA is restarted.

Example:
first start /dev/ttyUSB0 and /dev/ttyUSB1, if in the integration I use the device /dev/ttyUSB0 when HA restarts they become /dev/ttyUSB1 and /dev/ttyUSB2 but if I connect in SSH they always remain /dev/ttyUSB0 and /dev/ttyUSB1.

as per documentation I tried to create the udev rule (even if it worked without before) but nothing has changed.

i am desperate, i have been trying to fix it for 2 weeks without success, can someone help me.

thank you so much

Seems I’m seeing same issue, did you find a solution?
