Yes, but IMHO the OLED matrix displays for each button (8 buttons, 64x32 pixels) are incompatible with the event interface LED IOCTLs. Furthermore, using the special wacom IOCTLs it is possible to set the luminance levels, which the event interface provides neither. Please correct me if I'm wrong. Br, Eduard
