I did a search for this issue and I did not find anything helpful. My Dell laptop (Windows 7) is not seeing my Evo as an external drive via USB. I have tested the USB slots and they do work. I also took the phone to a Sprint store and it linked up to with their computer just fine. Not sure what is wrong but back when I moved from the Hero, I connected that to this computer with no issues in order to move pics, etc. When I plug in to the computer, the phone lights up but no window pops up asking how I want to connect (ie disk drive, etc). The phone does not show on the computer as a drive, and nothing in the tray. Anyone have any ideas? thanks.
