have u bought "USB DirectLink Cable" or something else.. i searched on google for this.. and site which sells/make them.. they claim "Its will be auto detected" but there is also a software which comes.. by which u can transfer the data
just to make sure that u have USB Direct link cable only ... this cable is having USB port at both end and in the middle there is some IC... for us it will be a notch sort of thing... u can have a look at
