| 46 | * History: |
| 47 | * |
| 48 | * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller" |
| 49 | * |
| 50 | * 2002-07-02 - 0.0.2 : basic working version |
| 51 | * - all axes and 9 of the 10 buttons work (german InterAct device) |
| 52 | * - the black button does not work |
| 53 | * |
| 54 | * 2002-07-14 - 0.0.3 : rework by Vojtech Pavlik |
| 55 | * - indentation fixes |
| 56 | * - usb + input init sequence fixes |
| 57 | * |
| 58 | * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3 |
| 59 | * - verified the lack of HID and report descriptors |
| 60 | * - verified that ALL buttons WORK |
| 61 | * - fixed d-pad to axes mapping |
| 62 | * |
| 63 | * 2002-07-17 - 0.0.5 : simplified d-pad handling |
Dominic Cerquetti | d518b2b | 2006-10-20 14:51:45 -0700 | [diff] [blame] | 64 | * |
| 65 | * 2004-10-02 - 0.0.6 : DDR pad support |
| 66 | * - borrowed from the XBOX linux kernel |
| 67 | * - USB id's for commonly used dance pads are present |
| 68 | * - dance pads will map D-PAD to buttons, not axes |
| 69 | * - pass the module paramater 'dpad_to_buttons' to force |
| 70 | * the D-PAD to map to buttons if your pad is not detected |
