Xperia S usb connectivity problems

[mode_lap]

I have some issues with the connectivity of USB, the computer recognizes the phone and PC Companion also, the file manager and transfer works correctly, but the problem is when I try to use the "back up and restore" or when I try to connect the phone and PC using wifi, in the  step of connect the USB, or when try to use my phone like modem with usb connectivity. Always PC companion freeze and no response and I can't open the "my pc" window, its freeze and no response also, But unfreezes immediately when I unplug the USB cable. I had tried on 3 pc different and the problem is the same, using windows 7. My phone is updated with Android 4.1.2 and build number 6.2.B.1.96

I am trying to connect my Xperia arc S with my pc (Win 8). It is not detected at all. My phone is able to charge through the cable but I am not able to detect it to transfer my data from phone to pc or vice versa. Please help

@Sonesh - Are you running Windows 8.0 or 8.1 and do you have USB 2.0 or 3.0 ports on your PC?

Why has there been no response to my problem with backups? 

I try and do a backup in PC Companion - it spends ages "preparing" my selected backup items before telling me the size of the backup and giving me a choice of what I want to call it.

The backup progress bar then moves (VERY slowly) before eventually the screen goes blank and the process stops responding, as shown in my post 2 posts back in this very thread.

I have been getting fed up to the back teeth contacting Sony over this issue and not one Sony contact has bothered to respond with anything useful either on here or by e-mail support. I need to backup my phone now for when my upgrade date comes.

PLEASE do not tell me to do a factory reset. I have tried this again and again and the problem persists in PC Companion.

I just want to be able to do a backup of my phone, something that was never a problem back on my old X10.

I have tried it on 3 different PCs, a Windows 7 machine, I have tried it on Windows 8, I have tried it on 32-bit installations, 64-bit installations, **bleep**, I have even tried a Windows XP installation!! It is the same result. The backup program in PCC looks like it is doing something, although takes forever to do it, then eventually the app stops responding. I am very knowledgable when it comes to PCs and software problems etc but this has me stumped and it would be nice if somebody from Sony could actually be bothered to give me some support?

Aren't we having no sense in checking cable connection between pc and mobile... In every post sony is addressing these issues first and then the OS ... They r not addressing the primary problem which are used to be the hot talks in a public forum... Their escaping tendencied talks r revealed by their customer replies... I m very much frustrated in using sony. Xperia slt26ii
