If the USB legacy mode came turned on in default settings, you could clear your CMOS to restore it to default settings.

Otherwise you'll have to get a PS/2 keyboard or a USB to PS/2 adapter (assuming you have that port in your mobo) to get a working keyboard and be able to get into BIOS.

agree

unplug computer power cord and remove the battery on the motherboard for at least 30secs then put back in and you should be good

Are you plugged into the USB slot labelled specifically for the KEYBOARD (usually at the top)?

The CMOS method will work, but I recommend this method:

1) Get manual and find the CMOS reset jumper (some have a button, but not most)
2) Turn off power supply (leave plugged in to maintain the ground for static discharge)
3) jumper the proper pins (actual jumper or piece of metal)

I don't have an answer. I am asking a question based on this thread. I have a MOBO where this same issue occurred. I cleared CMOS and the USB ports will not enable. There are no PS2 ports on the board? So now what? Board damaged for good?

You really should start your own thread.

I'll help if you send me a PM with the link of the new thread.

My quick answer is possibly the motherboard is bad, but try a different keyboard and different USB slots first. I won't reply here.
