SE W550i USB Problem

[Khaba]

my sony ericsson mobile is hung every time when i am attech with PC using USB.. sometime it automatically restart it... can any body have solution for this problem??

if i update framwire then it slove my problem???

I didn't understand exactly what is the problem, I have a W550i, when i connect it to the computer i get two connection mode, Phone Mode, File Transfer Mode. In Phone Mode it remains on but i can copy on and of the phone with SE File Manager cuz it's not seen as a hard drive by the computer. and in File Transfer Mode it shuts down and gets turned back on so the computer can see it as a removeable drive. when i disconnect it, it turn off an automatically turns on as a phone. I guess this is what happens to you, if not you might have a software problem.
