That makes it work nicely:

$ kldload u3g
(insert dongle)
dmesg:
 usb_test_autoinstall:571: Eject CD command status: USB_ERR_NORMAL_COMPLETION
 usb_alloc_device:1781: Found Huawei auto-install disk!
 ugen0.3: <Novatel Wireless> at usbus0
 ugen0.3: <Novatel Wireless> at usbus0 (disconnected)
 ugen0.3: <Novatel Wireless> at usbus0
 u3g0: <Data Interface> on usbus0
 u3g0: Found 2 ports.

Thank you. :-)
