As far as I know you the only thing that you set (after installing ASIO SDK) is that you define an environment variable called ASIOSDK_DIR
As I said, I'm on Linux, so I've never done this, but I would have expected that the output from compiling would indicate if it had been successfully included. Perhaps you can get some clue from the config.log (if compiling on Windows creates one - I'd expect some kind of log file).
Sync errors generally indicate that either your computer has run out of steam (for example not enough CPU power) or that there is a data bottleneck somewhere (for example the hard drive is too slow or badly fragmented). There's absolutely no guarantee that the device will perform any better with Audacity than it does with Cubase LE, but I must say, I can't wait to hear how it goes.
Good luck, and do let us know. You've obviously got a pretty good idea what you're doing to get this far, but if you get completely stuck and no-one else comes along, I'll see if I can find someone that knows about compiling on Windows.
