Modem Huawei E3531 not recognized


I am trying to install tne SMS notification integration, but till now the Huawei modem is not recognized as a modem, i have edited the /config/udev/10-gsm-modem.rules file
, ATTRS{idVendor}==“12d1”
, ATTRS{idProduct}==“15ca”
, RUN+="/sbin/usb_modeswitch -X -v 12d1 -p 15ca

Now i can get a discovered device (SMS notification integration) but when i try to configure it the modem can not be detected.

Thank you.


What version of HassOS do you have? What is the Linux Kernel revision on it?
I’m asking since on my case I had the same problem when updated to the version in the picture.

usb_modeswitch runned by itself and switch the USB Modem to Eth device, in the System information you could see that the USB modem was already used and provided an IP.

The solution in my case was to edit /etc/usb_modeswitch.conf file and set HuaweiAltModeGlobal to 1. After this unplug the USB device, restart the system, plug it back in and it works.
