ModemManager incorrectly grabs Bare Conductive Touch Board

[Stefan]

When connecting a Bare Conductive Touch Board device (http://www.bareconductive.com/shop/touch-board/), modemmanager grabs the /dev/ttyACM0 -device. This means the Arduino programming IDE cannot upload to the board.

I'm running 14.04 LTSl. Modemmanager is 1.0.0-2 trusty

WORKAROUND:

This bug can be solved by adding the line

ATTRS{idVendor}=="2a6e", ENV{ID_MM_DEVICE_IGNORE}="1"

to /lib/udev/rules.d/77-mm-usb-device-blacklist.rules.

I realise that this will block all Bare Conductive devices - however they are all Arduino-based and none will ever be actual modems - I can say this with some confidence as I am their chief development engineer!
