I originally had Vista Ultimate x64 on my computer and when root had come out for the Droid X I plugged it into my computer for the first time. Everything was detected fine and the drivers auto loaded themselves and root was successful. Flash forward to after vacation, still on Vista, I plugged the Droid into the computer and it wouldn't even detect a connection. It thought it was in an outlet. I tried unmounting the sd card, toggling usb dev, rebooting with the usb in, etc. and nothing worked. Now I clean installed and put Windows 7 x64 Ultimate and the same thing occurs. I put the Motorola drivers on my pc and the same thing occurs. My Droid doesn't even detect it is connected to a PC, no USB sign pops up on the Droid, nothing. I have tried refreshing Device Manager but nothing shows up. I am using the original cable supplied with the Droid X. Thanks for reading!
