Hi, great post, how i enable nunchuck report state, because the nunchuck it's connect the wiimote, but when i press the buttons on it, i can't see the info it's pressed,
For example:
when i press the button B on wiimote (code on python)

if (buttons & cwiid.BTN_B):
print 'Button B pressed' --> i see this
time.sleep(0.2)

but when i press the button C on nunchuck

if (buttons & cwiid.NUNCHUCK_BTN_C):
print 'Button C nunchuck pressed' --> i can´t see this
time.sleep(0.2)
