New HiFiBerry won't start

I'd just bought an HiFiberry Digi via order 4220. I pluged it on my rPi and it work neither on raspbmc neither raspbian. It (the HiFiberry) doesn't seem to start and aplay doesn't see it. I think that there're a problem with the hardware but I can't really prove it.

there is my "check-system.dac" :

root@pi:~# ./check-system.dac

there is my "/etc/modules" :

root@pi:~# cat /etc/modules
# /etc/modules: kernel modules to load at boot time.

# This file contains the names of kernel modules that should be loaded

snd-bcm2835
snd_soc_bcm2708_i2s
bcm2708_dmaengine
snd_soc_wm8804
snd_soc_hifiberry_digi

and there are these lines in my dmesg :

[ 9.833937] wm8804 1-003b: Failed to read device ID: -1
[ 9.845298] wm8804 1-003b: ASoC: failed to probe CODEC -1

I hope that will help to understand my issue.
