If you are just trying to connect the USB, then do the following;
1) Tap menu, and choose settings.
2) Tap wireless & networks
3) Go to USB utilities
4) Tap connect storage to PC
5) Connect the USB cable (Only now connect)
6) Tap the screen icon
7) Browse your phone through the PC. Your phone is connected like a thumbdrive.
Kies connection is a different thing. But if you just want a USB connection, the above should be what you want.
Cheers
