Hi, my Xperia U won't connect to my computer running XP. When I first connected via USB, Sony PC Companion v2.1 was installed and then auto-updated from the internet. Whenever I try to connect via USB, I keep getting the message: Code (Text): PC Companion was not able to connect to the phone. Please disconnect and connect again. When connected, Windows itself just recognizes the phone as camera ST25i. Can anyone help me out or is there some other way to transfer files to the phone via USB without PC Companion? Thanks!
