Gamecube Controller Adapter Problem

[masamunemori]

Hello.
I just bought a gamecube adapter to play on dolphin but while all the buttons and analog sticks work, the two shoulder triggers seem to remain on an on position.

I am not sure what the problem is, but there is no analog function. It is either fully pressed or not pressed at all. Does anyone have similar problems or can offer some advice?

The adapter I am using is:

Thank you for any help.

The only adapter which works perfectly is ulao's blissbox, but you may get some more life out of this one by setting the threshold to 99.
