Can some one please explain what is MessageContent and why we need it. Is there a way to calculate the MessageContent for particular dongle.

No, the method for the mode switch cannot be calculated. It doesn't even have to be a bulk message; in some cases a control message is needed.

The specific method is defined by the manufacturer of the modem - who has no restrictions what to do with the firmware.

There are several known methods used by usb_modeswitch; the usual way is to try these first on an unknown modem. If nothing works, then the included Windows driver can be analyzed (sniffed on) to find out what it does to switch the modem.

Be sure to read the documentation of usb_modeswitch.
