The standard USB 2.0 Header is a 10 pin.1 pitch header using the standard IDC pin numbering. The header has a key slot on the pin 1-9 side if enclosed. (The 10-pin IDC male graphic shown has the keying on the wrong side).Standard Headers contain two ports each, and have a missing pin for filled female connectors.PinNumber(IDC)PinNameDescriptionPort1VBus+5V Power13D1-USB Data5D1+7GNDGround for Power9No PinSpace of Filled Keying2VBus+5V Power24D1-USB Data6D1+8GNDGround for Power10DRAINGround for Shield DrainThe standard USB 2.0 Header is missing pin 9 (for keying), but logically pin 9 is for port1's Sheild GND. The sheild is left unconnected if a single port cable is plugged in to port 1. Dual Port hear connectors, share port 10 for both port sheilds.
Some Pinouts will show port 10 as NC, which makes both sheilds NC.A single port header is a 5 pin 1x5 and has the same pinout as port 1 of standard header, but wtih pin 5 as Shield Drain. It will work in eather port of the header, but port 2 is recomended due to the presence of the Sheild Drain.This is the most common USB 2.0 header (10 pin 2x5, missing pin 9) and it is pin compatable with the rare 8 pin 2x4 version (missing pins 9 and 10) and 10 pin 2x5 (no pins missing). It is NOT pin compatable with the very rare (10 pin 2x5, missing pins 10 and 2).Rare 2-missing pin header: (10 pin 2x5, missing pins 10 and 2)PinNumber(IDC)PinNameDescription1VBus+5V Power3VBus+5V Power5D1-Port 1, Data7D2+Port 2, Data9GNDGround for Power2No PinSpace of Filled Keying4D1+Port 1, Data6GNDGround for Power8D2-Port 2, Data10No PinSpace of Filled Keying.
Attach the front panel module (differs depending on the case design, consisting of power indicator, hard drive activity indicator, speakers, reset switch, power switch, etc.) from the case to the front panel header (FPANEL) on the motherboard. The pin assignments for the front panel header may differ by model. What i forgot to mention is, that my case already uses the mainboards USB 3.1 Gen 1 Connector. My card reader has an usb 3.1 Gen 1 connector as well. Therefore i have 2 USB 3.1 Gen 1 Cables which somehow have to fit into 1 USB 3.1 Gen 1 socket and 1 USB 3.1 Gen 2 Socket. I thought of sata because i have some sata connectors left on my mainbard.
