Running updated kies (10093_82) on XP laptop.
Samsung Galaxy S Vibrant (not updated to froyo yet, still 2.1)

Phone is set to prompt for connection type when usb is detected, and i've tried a connection as every type, installing all the hardware devices the phone brings up.

Loading up kies seems to work fine then with the phone is connected in Samsung Kies mode it just sits there "connecting" in the kies software endlessly.

If i try connecting the phone first, then clicking the tray icon to start Kies it just hangs on the loading splash screen (trying to connect to phone, again endlessly) requiring a force-close.

seems to have a problem installing MTP Device hardware (portable device category in system hardware) but theres no warning on it or anything.
