Yes, it comes with an adapter. When I first got the cable I took the microSD card out of my Android, popped in the Memory Cable card, connected the phone as a USB drive, and pulled the files off that. Later on I splurged $2.99 and got a microSD USB card reader.
BTW it is bidirectional - you can plug the end with the recorder into your amp or your guitar. Also, it works great with keyboards.
Just remember to turn on recording! The whole point is to have it always recording, don't wait until you "think" you're going to get inspired. I got a rechargeable battery so I wouldn't have to feel bad about leaving it on all the time.
