Hi,
I have an EM7355 module. It has USB PID 0x9041. From what I can see in the datasheet, the module should support MBIM. However, when I look at the USB descriptor, none of the interface numbers match MBIM (12 or 13) according to the USB Driver Developers Guide.
Am I missing something or is there another interface which supports MBIM?

The module can be configured for different sets of functions (MBIM, QMI, AT, NMEA etc) using AT commands. Look for UDUSBCOMP in this forum or download the Extented AT Command reference from source:
Hi,
Thanks for pointing me in the right direction
