And I agree about the test ports down the side, but still... I really don't think they'd put usb there... why would they need to test something that doesn't get used? I admit that there may be things on the board that aren't used (IE: USB?) My company makes 3 different electronic speedodometers, and while each one has different features and what not, each version has a part of the hardware that's unused. One doesn't use the oil light, one doesn't use blinkers, and one doesn't use the backlight. But every single one we ship can use all of them, the programming is what turns them off. Hell, they even have tempurature control... but that's completely unused and never will be... but it's there.... Anyways, I'm going to go test those pins to see if I can get a 5 volt. And sorry Mystik... I wish/hope just as much as you do that this process is just as simple as "the hardware's there, we just never knew how to talk to it" and we connect, compile/sign some drivers, and off we go! What we really should look at is how likely is it that the manufacturer would make some sort of external (outside the proc. on the board somewhere) connection to that usb... My biggest question though, above all else... Where would we be if afarre's curiosity wasn't so easily perked?

What you have, is the user connection signals that are NOT at the sync connector pins. Refer to the schematic of the Intel host adapter that Afarre posted at the beginning of this thread. What 'might' be available on the X50v is what I've shown. Since there is no signal conditioning circuitry in the Axim that I can see, an additional interface would be needed. All of this is pure speculation at this time. You won't find 5v anywhere on that connector - it's all 3.3v signals.
