icepap: cannot set velocity
Sometimes icepap refuses to set velocity, as it depends on acceleration internally and there can be some incompatibilities. But there is a fix, that is to reset acceleration then change velocity or something (can you comment @papillon @sebastien.petitdemange ?)
If velocity really cannot be set, it would be good to have a proper error message (see #253 (closed))
