Telit LE910-NVG

You probably want to dump 'dmesg' output when you power on the Telit
device.  If you don't see /dev/cdc-wdm0 or wwan0, that means the kernel
hasn't enumerated the device or hasn't bound it to a driver.  So what
I'd do here is:

1) do whatever you do to power on the telit device
2) grab 'dmesg' output after 10 seconds
3) grab 'lsusb -v' output, or better 'usb-devices' output

You should see stuff in dmesg like:

[    0.884476] usb 1-4: New USB device found, idVendor=1199, idProduct=a001
[    0.884480] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[    0.884482] usb 1-4: Product: Sierra Wireless EM7345 4G LTE
[    0.884484] usb 1-4: Manufacturer: Sierra Wireless Inc.
[    0.884486] usb 1-4: SerialNumber: xxxxxxxxxxxxxxxxxx
[    1.047084] usb 1-6: new full-speed USB device number 3 using xhci_hcd

if you don't see that kind of stuff, then the kernel was never notified
about the Telit device and there's no hope of it ever showing up; you
have to figure out that first.  That's probably related to the USB host
controller driver for your platform.

If the device does show up in 'dmesg', but the kernel isn't binding
qmi_wwan to the device, that could be a problem with module auto-
loading.  Try 'modprobe qmi_wwan' and see if that probes the device and
creates /dev/cdc-wdm0 and wwan0.
