Description Ville-Pekka Vainio 2012-09-29 14:39:50 UTC

Description of problem:
When attaching an Arduino device, in this case an Arduino Uno, modem-manager tries to open the ttyACM0 device and fails. The Arduino board notices this and it seems that the probes by modem-manager slow down the execution of the code uploaded to the Arduino board.

Version-Release number of selected component (if applicable):
ModemManager-0.6.0.0-1.fc17

The Ubuntu patches, which apparently have not been upstreamed, are here: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/910736

Comment 1 Jacek Pawlyta 2012-10-07 16:24:42 UTC

Confirming the same on Arduini Leonardo, when modem-manager is off 


$cat /usr/share/dbus-1/system-services/org.freedesktop.ModemManager.service 
[D-BUS Service]
Name=org.freedesktop.ModemManager
#Exec=/usr/sbin/modem-manager
Exec=/bin/false
User=root

Arduino UI seems to send sketches to the device, otherwise I get 

"Couldn't find a Leonardo on the selected port"
messages

Comment 2 Jacek Pawlyta 2012-10-07 16:53:34 UTC

adding 

# Arduino
ATTR{idVendor}=="2341",  ENV{ID_MM_DEVICE_IGNORE}="1"

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

at list 
fixes the problem also for Arduino devices, I don't think it will work for clones.
