HS2350 suspend/resume on Centos7.2

[Marc Jadoul <marc jadoul gmail com>]

Hello,

I have an HP elitebook 8770w. It come with a 3G modem hs2350. I found in the mailing list some comment of someone having similar issue as mine, long ago:

https://mail.gnome.org/archives/networkmanager-list/2012-November/msg00178.html

I am on a uptodate CentOS7.2. And when I suspend/resume, My modem does not work anymore. So the issue is not solved in this OS....

I have those versions:

ModemManager-glib-1.1.0-8.git20130913.el7.x86_64

ModemManager-1.1.0-8.git20130913.el7.x86_64

NetworkManager-1.0.6-30.el7_2.x86_64

Can we try to go futher on this issue? Can someone guide me on what to test / do?

Regards,

Marc
