Well to be honest, as evidenced by the following thread link, my experience with Yamaha has not always been stellar:

Back when I owned Tyros 1, I reported to Yamaha USA that my Tyros was not being recognized by my PC via USB.

I was 'repeatedly' assured that the problem is not a defective Tyros keyboard USB port, but that it must be something 'I was' doing wrong in setting things up on my PC from my end. Defective USB cable, improper PC USB driver, etc.

It took many months later (after repeated complaints from me, and then finally discovering on my own, and then having to prove to the head of YamUSA Tech support, that Yamaha Europe had already acknowledged this same problem months earlier, and had already issued an official hardware replacement fix for this problem, and 'only then' did Yamaha USA finally acknowledge that my T1 probably had the same defective USB Port part too, and only then did they finally agree to fix it, even though, by then, it was several months past my T1's warranty period. After all, I had initially reported the problem well within the warranty period, so this goes to show just 'how long' it took for them to finally become convinced that the problem wasn't my PC or something I was doing wrong, but a result of the deffective USB port on the Tyros itself. I gotta admit, that was truly a long frustrating experience. One would expect that because this was an acknowledged defective hardware part bug by Yamaha Europe, that Yamaha USA should have had knowledge about it too. Too bad it's left up to us as the customer to act as detectives to get things resolved.
