I used Windows 8..when the problem occured, I downloaded the latest HTC Sync for HTC One X, which is 3.3.17
But unfortunately the HTC Driver Installer that included was failed to be installed..
So I took a radical move, I reinstall my Windows 8..and tried to reinstall HTC Sync..
wal-lah, the HTC Driver Installer was installed successfully..
And the best of all I can use Internet Pass-through again! Cheers to my office internet speed, 1gbps..
I'm also on JB ROM right now..hope this will help you..
