A Question about USB Front Panel Inputs

Last response: in Motherboards

Hey there guys. I'm just completing my new build (my first real build in fact) and just have a question about my front panel USB inputs on the MOBO.
My MOBO is an ASUS P8Z68M-PRO[/url" target="_blank">.

When I turn on my computer POST lets me know that there is NO KEYBOARD DETECTED (even though I have a USB one plugged in). I've tried both the USB ports on the MOBO as well as the chassis. My first question is this: Is POST most likely letting me know that I have no (USB) Keyboard plugged in because I have incorrectly plugged in the front panel USB cables (wouldn't that just affect the chassis USB ports?). Or could it be because I cleared CMOS to work out a bug and now I have to plug in a PS/2 Keyboard (which I'll have to track down) to get it to detect so that I can pop in my MOBO disc and roll out the chipset driver update?

Because this is a new MOBO but an old balls basic chassis (that I don't even remember what the name of it was) the labeling on the cables is a bit different.. I'm currently in my University right now so when I get home I'll post what the cables are that are coming out of the chassis (pertaining to USB).. I thought a coffee would help me remember but alas, no. :sleep: 

Thanks for your time guys!

Are you using a gaming keyboard that has USB ports on the built into the keyboard (usually off the back or side)?

Not on this build no. Just a basic, cheap, Certified Data brand keyboard.

Does the keyboard actually work. Try repeatedly hitting the del key (or whatever your motherboard uses to get into bios) until the BIOS screen appears. If you get into the BIOS then the keyboard is working. If not plug your USB keyboard into one of the connectors on the back panel. I'm betting it will work (assuming the keyboard is not broken).

You don't need to get a PS2 style keyboard. Just a USB keyboard that works and is plugged in to a working USB port.

I didn't see any setting for enabling the USB keyboard in your BIOS program. I don't understand why a BIOS has issues recognizing a USB keyboard in this days and age, but I've seen it on other motherboards as well.

The way USB devices connect to the case, it's almost hard to plug them in incorrectly. Do you have the notch lined up?

If everything's good with that, when you plugged the keyboard into the MB, did you use one of the USB 2.0 ports (3 and 4) right next to the PS/2 port?

You might also try the USB 1 and 2 ports under the LAN port. Note-page 1-27 in the MB manual warns against connecting the keyboard to the USB 3.0 port.

Well, turns out it was the simplest of issues to fix. The keyboard was in fact busted :pt1cable:  Everything is hooked up and good to go now. Thanks a lot for the help though!
