I'm setting up a headless unRaid box. It boots off a usb flash drive, and I'd like to keep that drive on the inside of the enclosure. I got an internal USB 2.0 9 pin header cable, but it just doesn't want to discover the flash drive in the bios. It does boot off the flash when it's plugged into a normal USB port on the motherboard. Any ideas? thanks! https://www.amazon.com/gp/product/B06Y5C7DKH

| Of the 9 pins, only one row is being used. And I'm sure I got the red wire lined up with the Power+, on the opposite side as the dummy post and missing post. |
