Comment 1 for bug 701879

I used the packages arduino and arduino-core for Natty on Lucid (that is 10.04 LTS). I had an issue with getting Arduino IDE seeing /dev/ACM0 as serial port. As a workaround I created a symbolic link. That one I had to recreate each time I rebooted the system.

However, after installing librxtx-java in version 2.2pre2-3 the device /dev/ACM0 became visible and selectable in the menu. Now there is no need for the workaround anymore.
