Red Hat Bugzilla – Bug 861620
Blacklist Arduino devices
Last modified: 2013-02-18 02:02:33 EST
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):
The Ubuntu patches, which apparently have not been upstreamed, are here: https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/910736
Confirming the same on Arduini Leonardo, when modem-manager is off
Arduino UI seems to send sketches to the device, otherwise I get
"Couldn't find a Leonardo on the selected port"
fixes the problem also for Arduino devices, I don't think it will work for clones.
