Why the change?
Because u3g2.c is attaching to an USB interface and not the whole USB device.
This is to allow other drivers to hook on the other interfaces.
If you want to have exactly the same numbering like before, then the U3G
interface driver instances on the same USB device need to peek at eachother
to figure out the correct unit and sub-unit number.
Also to Vladimir, Are you sure that the 'u' devices are created with
the USB modem? They should only be created for uart devices...
