Battery charing issue - pls help!

---

My motoroid xt720 is having problem with battery charging and usb connection with PC through the phone USB small port:
-2 days ago I restored to original EU rom through this port successfully. Before this point of time,battery charging and usb connection with PC through the phone USB small port was OK.
-then I can not charge the battery and or connect to the PC through the usb cable via phone small usb port. However, I can now still use the same usb cable and port to restoreoriginal EU rom for the phone and use the same charger to charge the battery with external charging pad (not through phone.)

I use another charger with small usb port to charge the battery through the XT720 phone but it still can not charge.

Installing the new customed rom CronosX, but the same problem happen.

So I guess that the USB port on the phone has hardware issues or software issues with the phone.

Can someone give me advice how to check or fix this error? Thanks!
