Gamepad not properly detected by Emu.

[AnonLolicon]

So, I'm using the last build of PPSSPP (1.0.1) on my Ubuntu 14.04 32 bits, and I'm having an issue with PPSSPP not properly working with my Ps2 controller w/ adapter. The controller works perfectly on others emulators, but only on PPSSPP he is not detected (1.0), and in the last build I'm using, when I press Circle, it appears as a PAD_DOWN, I press Triangle, and appears PAD_UP, and this happens on both the QT and SDL versions. Any help will be aprecciated.
