Ok guys, with your blessings, I've gone ahead and tossed the Yamaha form letter & W9 form into the trash.

Mike: I'm elated to report that my Tyros USB connection now (following continued daily use) works PERFECTLY 100% of the time now, and in BOTH 'file utility' & 'Mass Storage HDD' modes as well. Mike, if you (or other Tyros owners here) are experiencing Tyros USB problems (flaky or no USB connectivity in either mode), I encourage you to contact Yamaha to arrange for the Yamaha Tyros USB hardware update. It completely corrects the USB problem, at least in my case. Since it's now (finally) an OFFICIAL Yamaha Tyros hardware fix, this IS covered under warranty by Yamaha as well.

As a pro Tyros player for almost 2 years now, it continues to REMAIN my performance keyboard of choice not only because of it's wide selection & high quality USE-ABLE (out of the box) sounds & styles, but for it's most USER FRIENDLY intuitive interface which includes its easy to view LARGE color LCD display navigation screen & buttons. I know better arranger keyboards may come along to entice & perhaps even grab my checkbook (Roland G70?! ), but for now, the Tyros remains at the top of my list, especially since I've now got it fully customized & personalized for just about each and every song in my repetoire. Just how much closer to perfection can you get?
