interfacing usb phone with MC using usb to serial adapter

[sakib501]

Hello, I am trying to interface sony ericsson k770i phone with attiny2313 microcontroller using usb to serial adapter. i am using a both sided female usb port where one side it takes male usb port of sony ericsson phone and another side takes male usb port of usb to serial adapter. now using that 9 pin serial port i want to use the rx tx and ground pin to interface with the microcontroller to retrieve sms. is it possible???

It is impossible.
The phone's usb is not host controller. It can not detect the usb to serial adapter.
