This is strange. src/sys/dev/usb/usbdevs says this:

product HUAWEI E140B		0x140b	3G modem

This means that your product is supported

Is this line in your usbdevs?

There is something very, very simple wrong. I just do not see now what
it is.

I have the feeling that your modem is not recognised while it should be
as it is known to FreeBSD.

need.
