Okay, so I'm having the same problem that apparently a lot of other people have had trying to get PDAnet working. Everything installs fine, but the s3c6410 Android ADB driver fails to install. I've done some searches and tried everything I could find, but I still can't crack it. I'm running Windows 7, using a non rooted Epic 4g, and I have the SDK installed. I tried manually applying the driver from the SDK's files, as was one of the suggestions, but it's not in the folder for USB drivers. I've beaten my head against the wall on this one, so I must be stupid. Is it located somewhere on my phone that I'm not seeing that I can pull it off and point to it? Or maybe there's a download somewhere online? Gah! Exploding brain!
