I have a footpedal (see altoedge.com) and fortunately there is a software for using it under linux (see http://code.google.com/p/footpedal/). The author of that software already solved an issue for me (see issues there), but there is no option to ask simpler questions.
Unfortunately prior to use the software I have to change the device permission each time I start linux. How could I change that to be done automatically at startup?
