Hi, My Samsung Galaxy S3 fails to connect to my PC at times. I've tried using the official Kies software and without. It fails on both instances. I usually get a Windows error (as below) when I connect the phone to the PC. I have tried the Kies "Troubleshoot connection error" option but I've had no luck in fixing it. The times this occurs seems random. At times, it will connect fine without any issues. Sometimes it fails to work and the error above is produced. I wonder whether it's the cable. However, as charging works fine, I'm not too sure about what exactly the cause is. Any help is appreciated.
