12d1:14db has ethernet interfaces (cdc_ether linux driver) when using the normal usb_modeswitch control message.
The author of the blog has used the alternative mode switch message intended for Android and gets serial (ttyUSB) interfaces, you do get rndis interfaces instead.
Since you both have the same E3533 then it must be a matter of dongle firmware difference
and there is nothing usb_modeswitch can do to fix that.

If you want old fashion serial interfaces then you'd better by an old fashion dongle.

Thank you for your info, I will try to contact the author to get some info about the firmware, and see what happen.
