The (incorrect) "Pen" (0x02) application usage used in replacement
report descriptors throughout the drivers leads to all tablets
recognized as a "direct" input device (i.e. a tablet monitor) by
recent kernels, which messes up desktop environments [1].

Replace the application usage with "Digitizer" (0x01) for each
non-display graphics tablet.
