HI all,
 I have an O2 with a 1600sw attached. when I run the confidence on it, I get  the following: "fp_1600SW: Unable to execute i2C backlight command"
when I run the display test, it is able to go through all of the test(brightness, focus, color guns...etc) without error. 

Does anyone have experience with i2C failure.. is it possibly related to not having the colorloc attached? 

The display seems to work fine otherwise, butI would like to get an understanding of the failure, if it is one.

Any feedback is apprieciated.
