Yes, Tyros OS version 1.20 requires 'Yamaha USB Midi Driver' version 1.61 or later. Check your email. I just sent you the version 2.08 which is working great for me.
btw: I just checked and there's an even newer version 2.09 now available. I'd assume, but not did not verify, if 2.09 supports the Tyros or not. Version 2.08 though, specifically states in its associated READ Me text file that it supports the Tyros.
