HTC Evo 4G
I got home, hooked the Evo to my PC and found that my Windows machine did not recognize it. I managed to find the solution in Android Developer Google Groups, you can read it here. We basically need to modify the entry in android_winusb.inf to add the VID and PID of HTC Evo. You can download the modified android_winusb.inf from here (right click on the link and select save as).
