Just to let you know, i've tried it on linux Fedora 20 (in a VM), and I needed too the chmod command. Plus, if I go to bootloader mode for firmware update, or if i press reset, connections to espruino then fails, even after quitting IDE, logout or reboot. But I entered the chmod command again after bootload mode or reset, and it worked.
