    USB Mobo Pinout?

    I assembled a PC using an Enlight 72500AZ case with an ECS K7S5A mobo (with an AMD Athlon 2000 CPU). Got nearly everything together and works fine (had to swap the motherboard, but it all works now).

    However, I cannot figure out the connection to the front USB ports. The motherboard has a USB header that shows pins 1. Verg_FP_USBPWR0, 3. USB_FP_P0-, 5. USB_FP_P0+, 7. Ground (Matches for pins 2, 4, 6, 8, too). The case connector is labeled, but no help to match. One Single pin, unmarked, and a three-pin connector labeled VCC D+. I tried the single connector on header 1 and on header 7, with the three connector on the other three header pins. Either way, no USB signal comes from the front of the case. (I used a USB mouse, and it works fine on the backside USB ports). What (simple, easy thing) am I doing wrong?

    Otherwise, overall, the case/motherboard combo works very well, lots of room, and the drives are all designed to slide right into the case.

    connect the front-mounted ports to the mainboard.
    Pin Signal Name Pin Signal Name
    1=VERG_FP_USBPWR0
    3=USB_FP_P0-
    5=USB_FP_P0+
    7=GROUND
    9=KEY

    2=VERG_FP_USBPWR0
    4=USB_FP_P1-
    6=USB_FP_P1+
    8=GROUND
    10=USB_FP_OC0
    When I hooked mine up I had 4 pins and 1 pin { 4 pin went to 1,3,5,7,and 1 pin to 9 } Yours might be {3 pin to 1,3,5,and 1 pin to 7 or 9}

    Re: USB Mobo Pinout?

    Obvious questions but...

    Are you sure the pins on the MoBo are active? This can be enabled/disabled in the BIOS on the Features Page I believe.

    Are you sure the USB ports aren't defective?

    Re: USB Mobo Pinout?

    <big>big</big> Anything is possible, but as for as active, if the other USB ports are working then BIOS is already set up properly for the USB ports. But it never hurts to check your book and see what it says about the other USB ports, but normally the setting in BIOS that activates USB is for all of them. Now there may be a jumper setting that has to be set to make those work, but I doubt it. Have you tried the above Pin out? Check in BIOS and make sure USB is enabled. It will look something like below. Also, did you build this computer and if so did you download the System Board Drivers?

    This page sets some of the parameters for peripheral devices connected to
    the system.
