I just got a huawei k3773 which is locked by vodafone. After unlocking, it can use any carrier. But there is a problem that it is totally different from previous data card like ec150. It can't be automatically recognized by usb_modeswitch and switched as a modem. That is to say, ttyUSB0~2 never displayed in /dev. And only usb storage recognized from the logread. No switching.
BTW, I found that this data card can connect to the network automatically without manually connecting. That is to say, even if you plug it into a 5V recharger, it can connect the network by itself as well. The LED can be solid blue. When plugged in Windows, it can create a virtual network card with IP 192.168.1.1. So it's mechanism is totally different. Any one has played it? How to make it work? Thanks!
