Huawei E5776s diagnostic port missing

[starbucks]

Hello,

I just received an E5776s Huawei modem and after installing the USB drivers I ended up with only the "PC UI Interface (COM17)" and no diag port.
Do you know what I have to do to have also the diagnostic port?

Thank you.

Might be so that it does not have it if it appears under network adapters or modems line too.
