doubleTwist not working with Epic 4G

I can confirm that doubleTwist works with Android devices on Windows 7, as I have synced my HTC Hero using it before. Why it doesn't work with the Epic, I have no clue. If you're phone is rooted, that might have something to do with it...

Maybe it's something to do with the drivers. Macs don't require the downloading of extra drivers. Sorry, I'm not too good with Windows 7 as I've been using XP since it first came out.
 
I appreciate the responses. Currently, my phone is not rooted (I only installed the USB driver on my Windows PC from that xda page).
 
Try this:
Go to Settings->Applications->Development
Select USB Debugging

Fixed my problem.

Yeah, that maybe why I didn't run into a problem with Doubletwist as since I am rooted and use Titanium Pro, I leave USB Debugging checked all the time.
