Download and install PC Companion from our website:

If you already have it installed on your PC, you can try to reinstall the program.

hi my sony xperia U  will not connect to my pc (XPERIA COMPANION) its charging but sony companion will not detect my device

I also have this problem! I have tried other phones, other usb cables and nothing is working! 
My phone connected fine a few weeks ago but since then I have had an update on my laptop (not sure if this is anything to do with it?!)

My laptop recognises my phone when it's in charge mode, but when I change to transfer files nothing happens.

Also tried device manager and updating driver but apparently I have no driver thingy on here 😕
I have the Xperia companion which also doesn't detect my phone while plugged in!

Any help would be greatly appreciated
