I just tried connecting it to my (rooted) Transformer Prime (Android tablet), used Optware's screen, and the Espruino is working properly ! :) So it confirms my problem is on the Mac side, though I still don't understand why and this is annoying ... :( (would be much more practical for developing, upgrading firmware, and so on).
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
