Hi all,
When I try to run [roslaunch flir_ptu_driver ptu.launch port:=/dev/ttyS0] I get the next error:

I never got this error before, and after my Ubuntu 14.04 was updated on October 1st 2015 this problem started there. I try to manually command flir driver use Arduino IDE serial terminal everything is OK, I can set or query it to certain position. so what is going on with my ROS?

fyi: Ubuntu error confirmation
