You can use dbus to easyshift/easyaim devices.
Have a look at the X_dbus_services.xml files in roccat-tools for the interface or inspect the actual bus with tools like qdbusviewer or d-feet.
To change the current profile use the roccatXcontrol applications.
There is no known way to alter the sensitivity besides loading a new profile.
