Connection problems with Clearpath Husky
Hi All, I am trying use the ROS stack for controlling a Husky in ROS Groovy. However when I launch the clearpath_base package with the example.launch file and specify the port as /dev/ttyUSB0 it gives me the following error: [ERROR] [WallTime: 1389718992.689323] Connection error on /dev/ttyUSB* or /dev/ttyS*. Will retry every second.
I have tried using ROS Hydro as well, in this case with the husky_base package and base.launch. I still receive the same error. Could someone please suggest what might be going on here?
I know nothing about the Husky, but can you compare the output of `dmesg` before and after you plug in the robot and list the permission you have on any device that is listed in there.
I was able to see the USB in 'dmesg' while plugging it in and out. It had to do with the group permissions. Thanks for the reply!
