Have you selected the Twinhan driver ? That could be the reason, If you 
have already done that,

most probably i2c communication failed, if you can launch the modules in 
verbose/debug mode you can see the Read/Write failures ..

If that happens check the experimental branch for the time being till it 
is merged into HEAD ..
