Also for me it doesn't work with a E1692 (product id 1446 before switch, 140c after). I can only get it to work if I edit /lib/udev/rules.d/61-option-modem-modeswitch.rules and comment out the line supposed to detect this model, and then install TIM Italy's branded Huawei Modem Manager, that came in the pseudo-cd drive in the usb key. Like that it always works, reliably. The only thing that I couldn't get to work yet were voice calls. I can make or answer them, but no way to play them on the speakers or use the mic.
