I'm running win xp and my captivate has the new update stock. Not rooted. I have tried many times with many different drivers. uninstall them all and tried again with no luck. In the device manager next to the S3C6410 Android ADB there is always a yellow " ! ". I loaded kies.uninstall it then install the newest one. Also installed the sdk. Still no adb driver will load. . wtf. mass storge works. Just not the adb. It's driving me nuts. thanks for any help. P.S. On my windows 7 box all loads fine.
