Must be missing something here. Using a newer case with USB 2.0 front panel connectors. The motherboards header does not have the "key pin". The manual is of little use (no pin layout description).

I decided to just cave man it, rotating the plug 180 both ways, windows (XP) just gives me an unknown device when plugging in a flash drive.

Rear ports work and the USB 2.0 card I added works fine. Would like to have the front panel connectors. Is it possible some pins are swapped? Best I can tell the onboard USB is NOT 2.0 but, 1.1.

Likely one of these (from Amptron web archive)... https://web.archive.org/web/20070623160549/ht … dusbmodule.html

Thank you!

I had broken out the multi meter and figured out which was ground and 5v (oddly, flipped per side of the header). Just couldn't figure out the data lines. "Layout 1" was a match. Working at 1.1 speeds, which is fine I just wanted them functional.
