- * - fine tune axes
+ * - fine tune axes (especially trigger axes)
* - fix "analog" buttons (reported as digital now)
* - get rumble working
+ * - need USB IDs for other dance pads
*
* History:
*
* - fixed d-pad to axes mapping
*
* 2002-07-17 - 0.0.5 : simplified d-pad handling
+ *
+ * 2004-10-02 - 0.0.6 : DDR pad support
+ * - borrowed from the XBOX linux kernel
+ * - USB id's for commonly used dance pads are present
+ * - dance pads will map D-PAD to buttons, not axes
+ * - pass the module paramater 'dpad_to_buttons' to force
+ * the D-PAD to map to buttons if your pad is not detected
