USB port's no working (Not detected by Bios)

Hi all.

I have a Asus P5KPL/EPU motherboard, with 8USB ports (4 in the front a and four in the rear).
Well, my problem is that it seems I have only 1/2 ports working, I don't know why.

I've tried to connect a flash drive and a mouse to every other port, and simply they would't be detected in Bios.
Also, only on one of the two ports would the mouse work, in the other, the mouse-light would be on, although the mouse wouldn't work... About the other 6 ports... Not even a signal, nor mouse nor pens would light up.

So, as the problem is visible in Bios I would guess this is an hardware issue. Can it be fixed?
If not, would it be a good idea to buy an USB hub to connect all my devices into the only motherboard Usb port that works? (I would use, for example, a keyboard, mouse, wifi adapter and at least a pen always connected.)

What about USB expansion modules? Sorry, I just heard about them, how do they work??

Thanks in advance,

Diogo

If this is only happening in the BIOS and not in Windows, then its likely a BIOS issue rather than a hardware issue. Try updating the BIOS and see if that fixes it. If it doesn't then I would start thinking of replacing the motherboard. If they work fine in Windows then it isn't an urgent need, but the fact that they don't work in the BIOS is an indicator that something isn't working as it should.

Hopefully the BIOS flash fixes it though.

Ok,
I did a BIOS flash.
Good news - My rear USB ports are now corretly working, thanks.

However, the front USB ports still show no signs of being willing to work.
Any advice on how can I solve this?

Thanks again
