Scott,

I agree with Riccardo - consider the Murphy's main software axiom: "Every software product has a bug."
It's an axiom, you don't have to prove it and it's true in generall...

Second thing: USB 2.0 supports transfer rate up to 480 Mb/s (USB 1.x supports up to 1.5 Mb/s), on usual Flash Cards up to 1 MB/s can be written, but "Flash ROM updates are installed via USB (running at midi speed: 32.5kb/sec)".
So I don't quite understand the meaning of the USB interface in Tyros, if it runs with the MIDI speed.
I have a digital camera with an usual Sandisk Flash Card. If I download (upload) the images from this card via USB 1.1 interface, 40 MB transfer takes approx. 80 seconds. The probability that the computer crashes during this time is ca. 0! (I took the time my computer runs; number of crashes during the last 6 months; I computed the average number of crashes a day and multiplied it with 80 seconds).

Regards

Marek
