Hi Lee,

The driver mentions that the first group of sensors have a WAI of 
0x3c: #define ST_MAGN_1_WAI_EXP 0x3c And when I print out the WAI read 
from the device: Requested device: lsm303dlh_magn - read WAI: 0x3c I 
guess I could have been lied to again by the board's datasheet again 
and the attached device isn't actually a LSM303DLH, but how can I tell 
for sure? 

On LSM303DLH you have to read 0x0a 0x0b and 0x0c registers, you have to 
find 0x48, 0x34 and 0x33. I think in the snowball there is the LSM303DLHC.

I just did that too:

  Device: lsm303dlh_magn: WAI: (0x3c)
  st_magn_common_probe():  IR: ID1 (0x48) ID2 (0x34) ID3 (0x33)

It appears the LSM303DLH does have a populated WAI register after all.

Now what? :)
