Hi, solved !

I know this thread is Abandoned, but if it can help future users, enjoy ;)

Have played recently at Assassin's Creed 1 & 2, and had some trouble to select
Xbox Series Gamepad in game, as mentioned by an anonymous here
https://appdb.winehq.org/objectManager.php?sClass=version&iId=11069&iTestingId=110090
and here https://appdb.winehq.org/objectManager.php?sClass=version&iId=19584.

But It's not a wine issue.

It's a backward compatibility of Gamepads.
Old Gamepads use this mapping :
Axis 0 : Left stick X abs
Axis 1 : Left stick Y abs
Axis 2 : Right stick X abs
Axis 3 : Right stick Y abs
Button 0
Button 1
etc
...
But new gamepad mapping is :
Axis 0 : Left stick X abs
Axis 1 : Left stick Y abs
Axis 2 : Left stick Z abs (Named LT on the controller)
Axis 3 : Left stick Y abs
Axis 2 : Left stick X abs
Axis 3 : Left stick Z abs (Named LT on the controller)
Buttons ...

Axis values are -32767 to 32766. Stick are centered with value 0,0 but when LT
and RT are not pressed, their value are -23767

So, /dev/input/eventX and /dev/input/jsX send new mapping, and Assassin's Creed
and Assassin's Creed 2 interpret new mapping as old mapping. So when you go on
the controller selection, LT/left Z axis return -32767, and the game
read/interpret that "right stick left" and unselect Gamepad.

I solve this issue in Assassin's creed by redoing the mapping with jstest-gtk
(or jstest), and select my controler /dev/input/jsX, as you can see on
attachement screenshot https://bugs.winehq.org/attachment.cgi?id=70098

I have not find a workaround for /dev/input/eventX for now

On Assassin's creed 2, you just nedd to configure controler in game option, by
changing Axis, it works fine with js and event controller.

It's really disappointing to see rating set to Bronze, just because Gamepad is
badly configured by the user while the game works perfectly (see
https://appdb.winehq.org/objectManager.php?sClass=version&iId=11069&iTestingId=110646)

Tested on Debian/11, workaround works fine with this versions of wine :
wine deb repos version : 5.0.4
wineHQ repos version : 6.0-stable
wineHQ repos version : 6.9-staging
wineHQ repos version : 6.9-staging

Hope it can help future Xbox Gamepad users on old Games
