An ignore should probably be added for Arduino.org devices too (there's two competing Arduino companies now, don't ask):
ATTRS{idVendor}=="2a03", ENV{ID_MM_DEVICE_IGNORE}="1" And, while we are here, perhaps also ignore the Pinoccio Scout (arduino- like device): ATTRS{idVendor}=="1d50", ATTRS{idProduct}=="6051", ENV{ID_MM_DEVICE_IGNORE}="1" -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/910736 Title: Add ignore rule for Arduino to udev blacklist Status in modemmanager package in Ubuntu: Fix Released Bug description: When connecting an Arduino or any Arduino-based device (like monome) modemmanager immediately starts exchanging data with the device, causing problems for software that works with these devices, namely serialosc and the Arduino IDE. Blacklisting the affected devices currently seems the best way to solve the problem, as found by doing a search for simular bugs, e.g. bug 842702, bug 807889 and bug 490194.
