I downloaded and installed Kies 1.5.3 and all uppdates on Windows 7 (32 bit). I plugged in my stock Tmobile (not rooted) Vibrant via USB and selected Kies. The Vibrant just sits there with a USB plug graphic taking over the screen and a series of dots going back and forth over the word connected. On the Kies desktop there is a corresponding "Connecting the Device Box" with a cylon style glyph going back and forth. Thats the way it stays forever, until I pull the usb cable. The Vibrant goes back to home screen and the Kies desktop connecting graphic goes away. Did I miss some step?
