Hi,

When i insert the Huawei-EM770 3G USB dongle, the minicom shows like below lines:

Display shows the network signal .But netwok signal is weak . If i enable the Data enabled option in Android Settings. The network signal is lost.

Huawei-EM770 3G USB dongle cannot work properly.

I attached the logcat file for radio interface .Please find it . Give any suggestion to make Huawei-EM770 3G USB dongle work in IMX6SL EVK in Android platform.
