USB drivers for HTC EVO? Where can I get them?

I am trying to test my app on my phone but I keep getting a message that says "Could not find an Android device to connect to. Please ensure that you have the phone connected, the correct drivers are installed, and the phone has a USB device debugging enabled."

Here's what I do have:

1) Phone is connected
2) USB device debugging is enabled.


I'm not sure if the correct drivers are installed. I have installed the Android SDK.

Where do I get the USB drivers for the HTC EVO. I tried the web site but I cannot find them.


Please help.

I am also having the same issue with my Motorola Zoom.
