Try to change the USB connection mode under settings > Xperia  > connectivity > USB connection mode. Change between MTP and MSC.

You can also try to update the phone using PC Companion or Update Service:

If you have tried all the advices above I would recommend that you try with a different USB cable or try against another PC.

If you have tried all the things above I suggest that you try to make a factory reset of the phone and then try to connect it to a PC again.

If you still can't get the phone to connect in MTP or MSC mode to any PC or with different cables, I suggest that you have your phone examined by a service center. Please contact your local support for more information:
