[Flightgear-devel] Joystick works in 0.7.6 but not in 0.7.7

[Mally <ma...@tk...>]

My joystick (Microsoft Sidewinder 3D Pro) works in 0.7.6 win32 but not in
0.7.7 win32.  I've tested all sorts of combinations of joystick input
parameters in system.fgfsrc and preferences.xml, even
added --control=joystick, but all to no avail.

I've read the PLIB/doc/js/index.htm and I'm confused as to the intention of
the min-range & max-range parameters. Are these saying that full-scale
defections of  each axis will deliver raw values of 0 and 65535 to fgfs, or
are they saying that if my js_demo range is -1.0 to +1.0, I should set
min-range and max-range to -1.0 and +1.0?  (I've tried this). What are
saturation and tolerance?

Is there a known problem with joysticks in 0.7.7 under win32 (in which case
maybe I can help investigate/fix), or am I doing something wrong?

More Detail:

js_demo recognises the joystick and each axis (0 to 3) ranges from
values -1.0 to +1.0:

The fsfs32.exe output looks like it also recognises the joystick:
