What type of USB cable is this?

What type of internal usb computer cable do I need?

• What type of internal computer cable do I need? I bought a used, older lian li case off craigslist. The case has 4 usb ports in the front, but no cable coming off the card internally. What type of cable do I need in order to hook these front usb ports up to the motherboard? There are 16 straight pins coming off the card. http://imgur.com/a/feLZU

• Answer:

  tldr: You need 2 2$ 5pin USB cables. You are looking for a USB 5 pin to 5 pin cable, you only use 4 of the pins. Your do-dad has 4 usb jacks (for 16 pins) and your motherboard will certainly have at least 2 usb pin outs, which will look something like http://www.pcpartsandcables.com/support/usbhelp/usbhelp2.php (and they will even be labeled on the board). Note: you might only have 1 of these connections on the motherboard, which means you would only be able to directly connect 2 of your usb jacks. There is one of these 5 pin cables listed http://www.short-circuit.com/categories/cablespc.php for 2 dollars. Look down at Figure 13 and 14 for nice pictures for connecting the front panel USB cables on http://windowsdevcenter.com/pub/a/windows/2005/02/23/build_perfect_budgetpc.html?page=3 page for what it actually looks like on your motherboard. Note: you can see (upside down) the white USB## stamped on the board. Issues: you will need to know the order of the pin out to make the connection. USB cables follow this scheme: RED POWER, VCC, SVCC, +5V WHITE P-, DATA-, SBD- GREEN P+, DATA+, SBD+ BLACK GROUND, GRND, GND And the Motherboard pinout is best described by a picture like the one on http://www.marnscda.com/PCWire101.htm which generally translates to : USB 1 PIN 1 RED: vcc, power, +5v PIN 3 White: P-, Data0- PIN 5 Green: P+, Data0+ Pin 7 Black: Ground USB 2 PIN 2 RED: vcc, power, +5v PIN 4 White: P-, Data0- PIN 6 Green: P+, Data0+ Pin 8 Black: Ground Pin 9 is missing so you can orient the layout 10 isn't used. The usb pinout from the back will be trickier. You will need to trace the following connections from the USB jack to the pin on the bottom of the usb dodad. Turn over the dodad so the pins are sticking out at you and so you can see the circuit (which you didn't picture) facing you. Each USB jack will be: left to right Pin 1 Gnd (black) Pin 2 P+ Green Pin 3 P- White Pin 4 Power: Red Each usb has it's own set of 4 pins on the dodad so you need to just work out the order to make the connection to the motherboard. A picture of the circuit would help.
