00depp80 Posted April 17, 2012 at 06:24 PM Share Posted April 17, 2012 at 06:24 PM Why can't I connect to brick via USB when I connected a external powersupply? Why the bricklets (ambient light and Humidity) doesn't work when I only connected to USB? Quote Link to comment Share on other sites More sharing options...
