You are wrong - it doesn't matter at which end of cable is PL2303, but you cannot cut cable between 2 connector if chip is in connector for cell phone. If chip is in USB connector you can cut cable and connect to hard disk. Windows will recognize cable like serial com port even WITHOUT cell phone connected. If not - than cable is fake. In previus post driver part is described very well - I can't tell you nothing more. If you need driver go to http://www.prolific.com.tw/eng/downloads.asp?ID=31
