Hello everyone,
I just got a secondhand huawei speedbox LTE mini 2 (E5786s) and it’s working fantastic with my laptop. After checking furthermore, I saw that it can be used as a wired modem by directly plugging it into the computer instead of using wifi. when I plugged it in, it didn’t work, unfortunately. I did some research and I found that usb_modeswitch must be used here.
so with lsusb I got:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 8087:0a2b Intel Corp. Bluetooth wireless interface

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
when inserting the modem for the first time I got the following output of journalctl -f

With usb_modeswtich already installed and showing on the logs, I starting looking on the internet on how to progress furthermore, I found this comment on askubuntu
So I made /etc/udev/rules.d/41-huawei_e5786.rules with the following data:
# Huawei E5786s
ATTR{idVendor}=="12d1", ATTR{idProduct}=="15ca", RUN+="usb_modeswitch '/%k'"
but even after rebooting and inserting the modem again, it didn’t work, now I get the following:
