I am new to both Chromebooks and to the USB Rubber Ducky (URB). I purchased 5 of the URB's to help enroll 270 Dell Chromebook 3380's. I looked up a couple of other scripts by people who have enrolled chromebooks and mine now starts like the one below. I used ducktoolkit.com to get my bin file and loaded it onto the sd card (tested it would bring up the "Hello World" on my machine and it did). When I plug the URB into the chromebook, it blinks green once and then does not do anything else. I tried pressing the button and nothing happens either. I also tried booting with it in, changing the initial delay times, moving it to a different port, and opening and trying a different URB to no avail. Any ideas?
