Problem with my Dance PAD

Hi, i buy this dance pad:

http://www.chipspain.com/en/promotions-1783/bargain-1694/ps2-1737/alfombra-de-baile-ps2-pstwo-1438.html (Dance PAD Model SD-008 Made in China)

I Connect it to a Destrok PS1-PS2/USB Adapter, i try this adapter with a ps1 controller and works fine when i push buttons and show correctly pushed in screen of Control Panel -> Printers and Devices -> Configure/Calibrate

When i plug dance pad on this adapter it doesn´t respond, i see in some webpages that i have to push first UP+START+SELECT to unlock it. I try pushing buttons on stepmania but it doesn´t respond.

This Dance Pad require any driver or configuration?

In StepMania go to Options / Test Inputs.

If the pad works in this screen then go to Options / Config Joy Mappings and setup the pad. After this you can use the pad with StepMania.
