Sierra Wireless EM7455 COM ports are Locked... Lenovo Why do you do something like that?

Lenovo why you lock the com ports on the Sierra Wireless EM7455 ?????

 

USB composition for the EM7455 is set to 9, which is MBIM only. I need to have MBIM and also COM ports for the AT commands and NMEA GPS data. So I need the USB composition 8

My question how to enable the com ports again ???

thank you in Advance...

Hello and welcome

That's not a Lenovo deal to lock the ports, more clearly, to choose appropriate default USB composition. MS and Sierra do that.

To change default USB composition change Sierra wwan card drivers installation configuration and reinstall them. Edit the configuration.ini file within the drivers package:
- [Default Values] section
- USBCOMP=x parameter (choose 8 as you want).

There was the same your thread about this case. Did you follow an advice in that thread, answer anything? No.
