[Rock-dev] supervision connections with canbus

[Chris Mueller]

Hi,

i have some problems with connecting my tasks to the canbus. Can some 
explain what kind of conditions
must be fullfilled in a supervision setup for an appropriate auto 
connecting?

Currently I always get an error of this:

= could not find a connection to the bus can0 for the input ports 
canJoystick, canSliderBox of 
Orocos::RobyPlugin::Controldev::Remote:0x7f90de42bc08{remote_joystick_com_bus 
=> can0, remote_joystick_name => remote_joystick}[] 
(Orocos::RobyPlugin::Ambiguous)
= Backtrace
