Hi Giacinto,

Thanks for your reply. My modem is: 

Hardware:
    Quectel
    RG500QEA_VH
    firmware revision: RG500QEAAAR11A03M4G

System:
    device: /sys/devices/pci0000:00/0000:00:14.0/usb2/2-2
    drivers: qmi_wwan, option
    plugin: quectel
    primary port: cdc-wdm0
    ports: cdc-wdm0 (qmi), ttyUSB0 (qcdm), ttyUSB1 (gps), wwan0 (net)

The result to lsusb -t is:

It was working for a long time till a upgraded the firmware and after that it always appear so I cant use ModemManager to connect the modem. I just tried upgrading to ModemManager1.16 but it seems to be the same (Also upgraded qmi and mbim to the last stable releases in https://www.freedesktop.org/software)<https://www.freedesktop.org/software>?

what is your modem and can you give the "lsusb -t" result for your device?
