I'm on Vista Ultimate x64 for what it's worth.
Hi ,
I was able to get this to work finally. I’ve been suspicious that the USB driver was the issue even after selecting it during the Android SDK process. I went to the Motorola site and downloaded a program that updates the USB Drivers for Windows. Link below:
USB and PC Charging Drivers - Motorola, Inc. USA
I used the “Clean and Reinstall” option.
Also, I’m not sure if it made a difference but besides checking the “USB Debugging”, I also checked “Allow mock locations”. I also checked the “Unknown sources” in the previous menu where “Development” is.
Hope this helps.
