Rocksmith USB Guitar Adapter Not Working

Thanks for your reply. To answer your question, yes, it does work in MME (I have no ASIO option), but the lowest latency is 30ms, inadequate for recording against the drum track that's already on there. Interestingly, even though it says "Not working," I was able to record a sample, but thus far have been unable to do so while monitoring the drum track. I've tried a variety of input/output settings on the two tracks, but so far have had no luck. Obviously I have a lot to learn about the basics of the process, but in all my searching through Adobe's how-to pages and YouTube tutorials, I haven't been able to get the setup to work properly.

Oh, and not sure if it's supposed to be this way, but I notice that MME gives me two options under Audio Hardware: one for input and one for output, while WASAPI only gives me one. With MME, I'm able to record the guitar while monitoring the drum track but a) the 30ms latency makes it pretty much impossible, and b) in any case it only records/plays on the left channel, regardless of how I adjust the input/output settings on the track itself as well as in Channel Mapping.
