Gamepad not properly detected by Emu.

Hi there,
Go to Settings / Controls tab - press on Control mapping, look down the list of keys on the left side, press on the X at the far right to clear that mapping, then press on the small + to change the key to whatever it should be, which in this case, is O on your PS2 pad.
BTW......Make sure the analogue light is lit up on the PS2 pad when doing this, to make sure the analogue axis's are activated.

Hope that helps.

Thanks for the reply, but my problem is not that, sorry if I didn't explained better. My problem is: Whenever I map a button on PPSSPP, example, for Circle, I try pressing Circle on my Controller, but the emulator interpreted as if I had pressed Down on D-Pad (I tested with Analog On/Off).
This happen only on my Linux, but on Windows, this doesn't happen, I press Circle, and in the emulator appears Circle.
Of course, this problem occurs too with Triangle, Square and Cross on my Controller, but only on PPSSPP, others emulators don't happen this stuff
