I had the same problem few months ago.
And I fixed it by doing this.
Give your phone for service
If you don't want to do this you can fix the phone your self
(I wouldn't recommend doing this if you don't have any idea what you are about to do)(so don't blame me)
First i Removed the screw and opened the phone then I used a soldering
And just heated the connection strip of the USB mini port the phone
(caution if the pin connect from one to another your phone could get serious problems so don't do anything it you don't have experience doing such things)
Then screw it back then try connecting the phone to your computer.
Hope it works.
It did work for me
