Connecting front USB ports to motherboard

[krneki]

I own Epox motherboard 8rda3+ and Chieftec case. I tried to connect my front (optional) USB ports but unfortunately, computer didn't boot on if they were connected. However, I don't use original Epox cable, maybe this causes problem.

Here is pins assignment for the cable (the are separated)
1 +5V
1 -D
1 +D
1 ground
1 ground
2 +5V
2 -D
2 +D
2 ground

and pins on the motherboard:
1
VCC
DATA0-
DATA0+
GND
Key (it's empty, without pin)
9

2
VCC
DATA1-
DATA1+
GND
Over current
10

How should I connect them together?
Thanks for help,
regards

aslong as their connected the correct way they should be fine, sounds like u have something shorting

I'm pretty sure that I haven't switched polarities. On the USB cable, some pins are joined together:
1. group: 1 +5V 1 -D 1 +D
2. group: 1 ground 1 ground
3. group: 2 +5V 2 -D 2 +D
4. group: 2 ground

If I understand correctly, pins numbered as 1 on the cable should be connected on pins from 2 to 10 on motherboard and pins, numbered with 2 on cable should be connected to pins from 1 to 9 on motherboard. I also tried vice-versa, so to change groups but computer also didn't boot up.
Any suggestions?

without physically looking at it, it would be to confusing to offer a suggestion
