Hi @hardikaghara1012,

What do you mean by ‘creasing’?

You should not have the `modemmanager` installed on Ubuntu - it interferes with the USB ECM interface between the mangOH and your host. See the release notes for Legato.

ciao, Dave

**_What_** requires 1.0.0 modemmanager ?

As @davidc says, modemmanager is _ **not** _ compatible with mangOH - as well as the release notes, search the forum for previous discussions.
