I have a USB device that needs to plug in internally into a motherboard USB header. For the moment I'm borrowing the USB header for the front panel USB 2.0 ports to make this work (and getting post errors about the front panel being disconnected since I'm not using all the pins), however there is another header on the board labeled "Internal USB/DASH" with a very strange and apparantly nonstandard pin layout (2x10 w/ several pins missing from the bottom row). Since this is labeled as being USB I suspect I can get the connections I need off of this header, but I have no idea which pins to use due to the odd layout.
Does anyone have information on the pinout of this port?
