The front USB connector broke. The connector' s ports are wired to USB ports 2-3 on the mobo. I need the pinouts for this mobo to be able to connect the new 4-pin+Gnd connectors (headers), pls. I have the manual, but it does not show the pinouts. I have verified that 2 of 10 pins carry +5V (Vcc), but all other pins appear not to carry a voltage (tested with just a voltmeter). The old connectors had two free pins and a ganged D+/D- connector for each port. I did not note down how they were connected (dumb, I know). The new 4-pin+gnd connector causes the message "USB Device not recognized" when a USB drive is plugged into the new front connector, and the USB mouse plugged into the rear connector no longer functions. I assume this is a wiring problem and not a software problem. The USB drive works fine in the rear USB port.
USB Pinouts K7SEM V1.0 SOLVED I found the answer. See: http://dtroeh.homeip.net/webshare/Drivers/K7SEM/woCPU/Manual/Pin Assign-USB.pdf This is a PDF file that contains photos of the USB pins on the motherboard, and the signals carried from those pins to the front panel USB connectors. I have verified that they work. They are NOT the standard Intel 4-pin header plus ground connections. Given back to front numbering: 6 to 10 on the top row and 1 to 5 on the bottom row. The signals are: 1 and 10: Vcc (+5V dc) 5 and 6: Ground, both signal and connector shell. 2 and 9: Not connected; not used. There is no point in connecting the extra grounds to these. 3: Data0- 4: Data0+ 7: Data1+ 8: Data1- In the USB metal shell there are 4 signal pins (underneath the white bar). Left to right they are: Ground, Vcc, Data-, and Data+.
