Summary: Joystick axes incorrectly mapped on Mac-OS-X

Initial Comment:
I do have a playstation-like USB joystick, but openMSX is not reading its axes correctly. The buttons seems to work fine.

As almost all playstation-like USB joysticks, it has the following configuration:

Button #1 : Minimum = 0, Default = 0, Maximum = 1
Button #2 : Minimum = 0, Default = 0, Maximum = 1
Button #3 : Minimum = 0, Default = 0, Maximum = 1
Button #4 : Minimum = 0, Default = 0, Maximum = 1
Button #5 : Minimum = 0, Default = 0, Maximum = 1
Button #6 : Minimum = 0, Default = 0, Maximum = 1
Button #7 : Minimum = 0, Default = 0, Maximum = 1
Button #8 : Minimum = 0, Default = 0, Maximum = 1
Button #9 : Minimum = 0, Default = 0, Maximum = 1
Button #10 : Minimum = 0, Default = 0, Maximum = 1
Button #11 : Minimum = 0, Default = 0, Maximum = 1
Button #12 : Minimum = 0, Default = 0, Maximum = 1
Page: 0xff00, Usage: 0x1 : Minimum = 0, Default = 0, Maximum = 0
Z-Axis : Minimum = 1, Default = 1, Maximum = 1
Z-Axis : Minimum = 0, Default = 128, Maximum = 255
Z-Rotation : Minimum = 0, Default = 128, Maximum = 255
X-Axis : Minimum = 0, Default = 128, Maximum = 255
Y-Axis : Minimum = 0, Default = 128, Maximum = 255
Hatswitch : Minimum = 0, Default = 15, Maximum = 15

This is mapped as follows (on analog mode):

Digital stick = Hatswitch
Left Analog stick = Axes X and Y
Right Analog stick = Z-Axis and Z-Rotation

When working on digital mode, both the Digital stick and Left Analog stick are both mapped to use the axes X and Y. The right analog stick is mapped to the buttons 1-4.

The openMSX reacts to the joystick as this:

Digital Mode: the game reacts as if the joystick is pointing left always.
Analog Mode: The right-stick works for up/down and the game still reacts as if the joystick is pointing left always.

Message:
My guess would be that this is an SDL bug... openMSX uses the information
it gets from SDL for joystick.
