That's still usb_modeswitch. Windows is sending a specific message to the Huawei device telling to use a specific mode, and it switches to that mode. After reboot to Linux, it's still in that mode. But if you coldplug the device while in Linux, usb_modeswitch sends a message to the device that is different than what Windows sends. On Linux with ModemManager, we would prefer to use the "Windows" mode since that is more capable. Unfortunately, usb_modeswitch needs changes to send the correct message to switch to the "Windows" mode too. All that said, if possible ModemManager should try to support the non-Windows cdc-ether mode too, but there may be bugs with that.
