Sony x10i USB Connection Problem

[#1]

I've bought my x10i at January 2011, it works fine all the time. However, when I tried to connect it to my laptop via USB cable it doesn't work! It still can charging the battery but it just can't detect the USB connection. At the same time, the charging will delay like for 5-10 seconds then only the front light will have yellow light and show it's charging. I've send it to the shop for checking but they said the phone's USB port is fine. They can't even figure it out what's the problem of my phone. Can;t connect to laptop mean there will be trouble on install the apps as well as run PC Companion. This problem make me become harder to move my file in SD card cause it can;t connect to the laptop. Anyone had experience like this before? Any solution?  Can anyone help me to solve this problem? Thanks.

Have you tried connecting to another PC/Lap or another USB port? As you mentioned that you are able to charge, I don't think there is anything wrong with both your phone USB port or the USB cable.

You could try re-installing the drivers on your PC from this link  http://developer.sonyericsson.com/wportal/devworld/search-downloads/driver?cc=gb&lc=en

Ya,I've tried to connect it by using another USB Cable and also to another laptop/PC as well...But it still not working. The phone shop that I look for help also told me that they never met this kind of problem too. They say maybe is the software problem but can't confirm me.

You may try Suze's suggestion. If your are still unable to resolve the issue, I suggest performing a Factory Data Reset. This will erase your phone memory completely (SD Card not affected), do remember to backup. Good luck.

Goto Settings>Privacy>Factory data reset.

I have the same thought to format it as well. Will put it as my last choice if it really have no other way to fix. Thanks a lot.
