HID: uclogic: Switch to Digitizer usage for styluses
Browse files Browse the repository at this point in the history 
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.
