EC25GGB module in Dell notebook only see DM port

Hi,

My problem is that i have a EC25GGB module and in device manager only DM port is available, NO AT or any other port is visible.

I tried driver update and i tried updating the firmware. At the firmware update i got (FAIL, detect port fail), but i chose the port number of DM Port.

We’d like to use this module with the Dell Latitude E5530 notebook. What can i do?

Hi
I will send you the latest driver via email, please check, thank you.
Best wishes
