All USB ports locked because of wrong BIOS command- how can I re-enable them ?

[br112]

following a bad BIOS command all my USB ports are locked and I can't access the PC neither through keyboard nor mouse.

I have a Pavilion P6-2370ef with a H-Cupertino2-H61-uATX motherboard

Is there a way to reset BIOS to manufacturer's state ?

I have the HP specs for the motherboard which deals only with the CMOS and BIOS PASSWORD jumpers.

- I have removed the CMOS battery

- I have done the reset of CMOS and BIOS PASSWORD through the proper jumpers as described in the HP specs of the motherboard.

- HP user support has no answer.

but the USB ports are still locked.

There is a BIOS_RECOVERY jumper but I don't know how to use it.

Many thanks in advance to somebody who has an idea

the correct method was to :

-power down the PC

-change the position of the CLEAR_CMOS strap

-power on the PC

the USB ports are now usable.

- down power the PC

- put the CLEAR_CMOS strap in its initial position

- power on the PC again...

the HP specs did not include power on after change of position of the strap.
