Hi all

I have some questions of this. I used the SIM5218 module to connect DM3730.It can call and send message, sometimes i surf the web ,the device would disconnect but  sometimes not .It printed:

    Hi Jognny,

    Are you trying to connect this module on EVM or your own device?

    Please connect this module via external powered USB hub and give a try.

    Kindly enable USB debug support and provide log.

     Location:
        -> Device Drivers
          -> USB support (USB_SUPPORT [=y])
            -> Support for Host-side USB (USB [=y])

    Thanks and Regards,

    I  am connecting this module on EVM .and in addition to have another problem too . The ppp data disconnect  when surfed the internet (android system).

    I used the command (adb logcat -b radio)

    Some of the printed log :
