Hi Jiri, at last!!

HID is reporting the axis' range correctly:

Now, why joydev's input_dev is reporting -127, 127 just for the two first axis?

Another problem is that the joystick reports 12 (1-12) buttons and
joydev get's 0-12 (13 buttons):

May 30 23:19:07 jobim kernel: [ 3316.543461] hid-debug: input Button.0001 = 0
May 30 23:19:07 jobim kernel: [ 3316.543466] hid-debug: input Button.0002 = 0
May 30 23:19:07 jobim kernel: [ 3316.543470] hid-debug: input Button.0003 = 0
May 30 23:19:07 jobim kernel: [ 3316.543474] hid-debug: input Button.0004 = 0
May 30 23:19:07 jobim kernel: [ 3316.543478] hid-debug: input Button.0005 = 0
May 30 23:19:07 jobim kernel: [ 3316.543482] hid-debug: input Button.0006 = 0
May 30 23:19:07 jobim kernel: [ 3316.543486] hid-debug: input Button.0007 = 0
May 30 23:19:07 jobim kernel: [ 3316.543490] hid-debug: input Button.0008 = 0
May 30 23:19:07 jobim kernel: [ 3316.543494] hid-debug: input Button.0009 = 0
May 30 23:19:07 jobim kernel: [ 3316.543498] hid-debug: input Button.000a = 0
May 30 23:19:07 jobim kernel: [ 3316.543502] hid-debug: input Button.000b = 0
May 30 23:19:07 jobim kernel: [ 3316.543506] hid-debug: input Button.000c = 0
