# Find the Nunchuck
######################################################################
#
# This script locates the Nunchuk uinput device by searching the
# /sys/devices/virtual/input pseudo directory for names of the form:
# input[0_9]
. For all subdirectories found, check the ./name pseudo
# file, which will contain "nunchuk". Then we derive the /dev path
# from a sibling entry named event[0_9]
∗
. That will tell use the
# /dev/input/event%d pathname, for the Nunchuk.
