USB pinout
I am familiar with the standard USB pinout (red, white, green, black) but have installed a new board in a case which has an unusual cable for the front USB connection. The plug fits the motherboard but has 10 wires (red, orange, white, yellow, grey, green, black, brown, purple). The header on the front USB port is labelled and suggests that green and blue identify channels 0 and 1. Is anyone familiar with this wiring protocol? Many thanks.

that cable is for the front audio connections
Sounds like the front panel audio header cable.

There are headers on the front USB/audio panel. These are labelled USB and audio, and the cables are not interchangeable. Thus the one with the 10 wires must be the USB. The audio cable is also strange, It only has 5 wires, although 2 are split to each go to 2 pins in the plug making a total of 7. I would expect 9 going by the header on the motherboard.
