My device is not rooted.
I tried with Windows XP, Vista, and Windows 7.
I install the SDK, downlosd the necessary packages, plug in the the device, and enter "adb devices" on the command line and it doesn't recognize my device. Furthermore, PDANet doesn't recognize the device when I plug it in.
And no, I don't think its harsh. The Samsung Tech Support was useless while their product was not working as it is supposed to.
