[SOLVED][Linux][Wii] guitar doesn't work

[efemache]

Hello,

I'm using Linux (Debian testing x64) with the latest code from github (4.0-9124).

I can start any Guitar Hero games (Metallica, Greatest Hits, World Tour, Warriors of Rock), but if I try it with a Nintendo Wii remote (motion plus inside) and the guitar from Guitar Hero 3, I have the same problem :
every button works ('+', '-', the analog stick, ...) except the fret buttons (green, red, yellow, ...).

Any idea ?

I don't know if it's a bug but I'm pretty sure it doesn't come from my guitar because I tried 2 guitars.

Thanks
