Default [Q] Cannot Connect My Phone To PC

I have my One X for like 5 months now. Everything was working just fine and I was able to connect my phone to my MacBook with no problems. I was able to transfer files using HTC Sync Manager as well. However, recently my phone would not connect to any computer. When I connect my phone to the computer it just starts charging, no other notification shows up in the bar. Sync manager would not see the phone as well. I don't know if its the software or my phone. I tried Windows and OSX; I tried different USB cables; Factory Reset did not help; Debugging is on. Its frustrating! It seems like people encounter this problem, but no real solution or answer has been found. Do you guys know something about this?
