New Build - USB and Audio problems

Successfully built a unit last month, with recommendations and advice from your good selves, but trying to add the finishing touches I have run into a few problems.

The case is a JNC 4JA 8626 300watt with front panel audio, USB and 1394 (Firewire!).

The motherboard is a Syntax Skt A AGP Via KT266 DDR/SDR ATA 133 Sound/Lan/USB2.0.

The identifications on the wiring for the front mounted audio, USB and 1394 do not tally with the information in the board manual.

For instance: the manual refers to the USB connectors, pins 1 to 8, as USBVCC3 +5v dual, USBVCC3 +5v dual, USBP4- data signal port 4-, USBP5- data signal port 5-, USBP4+ data signal port 4+, USBP5+ data signal port 5+, GND ground and GND ground.

The case wiring for the 2 USB sockets consists of 2 off 4 core ribbon cables identified as VCC1, DATA-1, DATA+1, GND1 and VCC2, DATA-2, DATA+2, GND2.

I have tried connecting VCC1 to Pin 1, DATA-1 to Pin 3, DATA+1 to Pin 5 and GND1 to Pin 7 etc but the computer hangs. The manual warns of this possibility!

As usual, all assistance and advice greatly appreciated.

I,ll detail the other problems later!!!

I have this info it might work.Usb connectors to motherboard

Just follow the labels on the pins
1 +5V = power or pwr = VREG_FP_USBPWR0 = VCC 1
2 +5V = power or pwr = VREG_FP_USBPWR1 = VCC 2
3 USB_FP_P0- = DATA –1
4 USB_FP_P1- = DATA –2
5 USB_FP_P0+ = DATA +1
6 USB_FP_P1+ = DATA +2
7 GROUND = GND 1
8 GROUND = GND 2

Now I'm totally confused.

sorry the formatting on this site lets me down. Basically I have listed the pins which you should be able to identify from your mobo or mobo manual. I have given 2 different descriptions of the use of the pins and from this you ought!!!! to be able to identify the cables from your usb sockets and stick them on the correct pins on the mobo. It is probably best to separate the pins from the 2 usb sockets and do them 1 at a time. If this does not help e-mail me the descriptions on each cable and what your mobo manual calls each pin.

Many thanks. I'll continue tomorrow, with a clear mind I hope.

Have deciphered your second post and the connections are identical to my original.
However, with a clear mind this morning I reconnected the wiring, one USB socket at a time, and tested the first before connecting the second, and the two sockets are now OK. Why I do not know!

Many thanks for your interest and advice. I shall close this thread now and open a new one for my audio problem.
