@KBird,
hahaha, found it. I have checked each component once again and nothing. Being quite resigned I decided to check Warthog stick (I know, it was waving a dead chicken...). So I unscrew the grip and plug it to female connector of PS/2. Of course... nothing, it's dead. So I turned the grip upside down to unplug it...

"Hmmm... WTF? How is it supposed to work? One cable is not connected at all! OMG, the other are soldered to wrong pins!"

You know what happened? I used this schema:

but I have soldered female connector 'upside-down', I mean mirrored! GND replaced with DATA, SCK with CS, VCC soldered to nothing biggrin

Ten minutes later everything started to work :-)

Regards,
sun
