To those having trouble getting the "Android 1.0" driver to install and not finding Samsung. Not only did I install the Samsung driver posted a couple posts above, but also: when right clicking on the Android 1.0 device and updating driver, then choosing "Let me pick from a list" I then chose "All Devices". There were about 6 different entries for Samsung (Samsung, Samsung Co., etc) and one of them had the Android ADB Interface entry, which worked. Originally I was just looking under "portable devices", which isn't it.
Hope that helps!
