>Description:
Connecting bluetooth mouse through bthidd daemon gives wrong button mapping: right button is swapped with middle button.
Looking at HID Usage Tables and 'xev' output it seems to me HID that hid "usage" value is incorrectly being used as button index. Since ps2 mouse seems to map right button to 3 and middle button to 2, apropriate fixup has to be done (similar fixup seems to be done in ums.c). Following patch makes all 5 butons work in my setup (including mouse wheel buttons).
>How-To-Repeat:
Just configure bthid mouse and try to invoke right-click action in some graphical interface.
