I have tried two different computers. One running XP one with Windows 7. They see my HTC One (M7) just fine but they dont see this HTC One X. Do you think there is something possibly wrong with the phone? The phone seems to be charging through the USB. If it was a driver issue I dont see why the HTC One M7 would connect. I have tried installing HTC Sync also the all in one toolkit drivers.
In fastboot it shows fastboot ac instead of fastboot usb
