1 VCC Red +5 VDC
2 D- White Data -
3 D+ Green Data +
4 GND Black Ground

So grab a multimeter and test for a +5 VDC... :P If there isn't one, then either they want an external power or they're not usb...
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?

(edit, 5 minutes later...) Didn't find any power wires... but after testing those four pins my axim still works! So maybe they're just extra... designed the connector and the pins then pulled something out of the hardware that was going to use them right before they were ready to be produced... rather then redesign it they simply don't connect to anything.
Has anyone looked at where the pins go on the board? If they have traces made for them... then I wouldn't be surprised at all if it's a usb connection... too convient that it's four pins, the proc. has usb hosting capabilities, AND hpc has been putting usb in alot of thier devices. HPC does make the axim right? Or did they just design the electronics?
