Question about Abit KG7-Lite Motherboard
Abit Kg7-Lite motherboard USB2 pin assignments needed. I have 2 front mounted USB ports (which I cant remove or replace since they're built into the case) and instead of the integrated plug, there are many separate wires with single connectors on the ends, to connect them to the motherboard. I need to know exactly which pin in USB2
to connect each wire to. The manual names the pins in a chart, but does not show me where each pin is located in Usb2 on the board. where can I get this information?!
Lay case down with the bottom in front of you. Looking straight down at the row nearest the case bottom reading right to left there will be two rows of four pins.
Reading right to left the row closets to the case bottom the first lead is vcc1, next usb1-, next usb1+ and grnd1.
Top row reading right to left is vcc2, next usb2-, next usb2+ and grnd2.
I just replaced bad caps on my kg7 and had to remove the motherboard for the repair so I just reinstalled my front case usb ports.
Help this helps.

Tips for a great answer:
Mar 23, 2013 | Computers & Internet
click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually ((red white green black)) make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts
FRONTX USB Type A Internal
Half of large bay
USB type A female
1x5 header connector female
USB cable (UL 2725)
Length - 2.5 feet (762 mm)
Red: + 5V / Voltage + / VCC
White: D - / Data - / USB -
Green: D + / Data + / USB +
Black: GND / Voltage - / Ground
Black: S-GND / Over Current / Shielding
The S-GND wire is fatter and can be easily recognized. The connection of S-GND wire to the header pin is optional.
HEADER CONNECTION GUIDES
Diagram 1: On most motherboards, the USB header/pin-out consists of 9 pins arranged in 2 rows, which allows for 2 USB connections (i.e. USB1 and USB2). Normally, the pins for USB1 and USB2 are in seperate rows.
Diagram 2: Simply plug the connector onto the 5-pins row, and make sure that the pin assignments and wire assignments are matched correctly.
Diagram 3: Alternatively, you can plug the connector onto the 4-pins row, and leave the S-GND wire unconnected.
You might have to rearrange the wires to match with the pin assignments, or change the header connector if necessary, depending on the layout of the USB header.
On some motherboards, there is a NC pin in the USB header. You can connect the S-GND wire onto this pin. NC simply means "no connection" and NC pin is an "empty" pin.
2X5 PINS HEADER
Refer to the diagram below, for 2x5 pins header, simply plug the connector onto one row of the pins, and always make sure that pin assignments and wire assignments are matched correctly. You might have to rearrange the wires if necessary.
2X4 PINS HEADER
Refer to the diagram below, for 2x4 pins header, simply plug the connector onto one row of the pins. Please note that there is no S-GND pin in this header. You can leave the S-GND wire unconnected. You might have to rearrange the wires if necessary, in such that the wire assignments and pins assignments are matched correctly.
ACTIVE PINS NOT IN THE SAME ROW
On some motherboards, the 4 active pins are not located in the same row, as shown in the example below:
To connect to this type of USB header, you need to change the header connector to 2x5. Simply rearrange the wires within the 2x5 connector to match with the pin assignments. If the green wire is connected to the USB2+ pin, the white wire must be connected to the USB2- pin. The red wire can be connected to any +5V pin, and the black (GND) wire to any GND pin. If there is no S-GND pin provided, you can leave the S-GND wire unconnected.
hope it helps
