Configure USB GSM Modem

[fjsousa]

Hello,

I'm trying to configure a USB GSM Modem on my CentOS 7 server to interact with my gammu service. My USB GSM is detected but doesn't attached to any ttyUSB. What I need to do?

Thank you.

Have you enabled the 'ModemManager.service'? Is it running?

[fjsousa]

How can I see that?

I guess it's running because with another USB GSM modem works perfectly...

Thank you

It's showing up as a USB mass storage device "[186403.013349] usb-storage 4-10:1.0: USB Mass Storage device detected". That means it needs usb_modeswitch run against it to flip it to modem mode and that's something that ModemManager is meant to do for you. It doesn't appear to be installed - perhaps just yum install ModemManager and see if it helps.

Hello TrevorH,

I've installed the ModemManager and it's running now.

Code: Select all

systemctl status ModemManager.service
● ModemManager.service - Modem Manager

Now in my messages logs appears this:
