Sorry, but EB 1.4 does not support debugging with Chrome Inspector (the docs for 1.4 incorrectly stated that it did, and have since been corrected), but you can debug through Chrome using Weinre. It's documented on our new TechDocs site for EB 1.4. Weinre "officially" supports Jelly Bean but should also work on any higher version that can run node.js.
Enterprise Browser 1.5 will support on-device debugging with Chrome Inspector, and is scheduled for release in a few weeks.
I hope this helps.
