I cannot explain it, but udev is now working correctly.
$ udevadm info /dev/cdc-wdm0
P: /devices/pci0000:00/0000:00:1d.0/usb3/3-1/3-1.6/3-1.6:2.12/usbmisc/cdc-wdm0
N: cdc-wdm0
L: 0

The modem is now listed
$ mmcli -L
/org/freedesktop/ModemManager1/Modem/0 [Sierra Wireless, Incorporated] Dell
Wireless 5570 HSPA+ (42Mbps) Mobile Broadband Card
but I cannot enable it
$ mmcli -m 0 --enable
error: couldn't enable the modem:
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.WrongState: modem in
failed state'
may this be related to the missing SIM card? I am not going to add the
card, but I would like to use the GPS of the WWAN. It this possible at
all?
Thank you,
Giuseppe
