Not detected

[1403]

Hello,

My Xperia S is not detected by the latest PC companion on a Win 8 PC. It's only charged when connected to PC with the usb cable. At the same time an Arc phone is detected on the same PC by the same PC companion when connected with the same usb cable (both its own usb cable and Xperia S' usb cable).

Does it mean that the problem is not in PC, not in Win 8, not in PC companion, not in usb cable, and only in the phone Xperia S? 

And if it does what can be wrong with Xperia S? Otherwise it works perfectly.

Please help - cannot upgrade to JB / offload media.

If PCC is installed then when it shows to install driver you should get a box that says install anyway or words to that effect

I checked with Win7, same story. Luckily, I could upgrade to JB via update center / wifi. But re connection to PC - have you ever heard a phone to miss / lose its usb data transmission functionality (while charging is still fuctional)? Looks like this is the only scenario, because I checked lots of cables, PCs, Win7/8, ICS/JB
