Hi folks,

I am looking for some configuration hints for a Logitech Cordless
Optical Trackman. AFAICS it requires an "AngleOffset" parameter
to be set to -32' in the Hal configuration, but since Hal has been
kicked out (good thing) and keyboard and mouse settings in xorg.conf
are ignored by default, too, I wonder how this can be done for udev?

xinput shows me these params to set:

Device 'Logitech USB Receiver':
        Device Enabled (121):   1
        Device Accel Profile (249):     0
        Device Accel Constant Deceleration (250):       1.000000
        Device Accel Adaptive Deceleration (252):       1.000000
        Device Accel Velocity Scaling (253):    10.000000
        Evdev Reopen Attempts (238):    10
        Evdev Axis Inversion (254):     0, 0
        Evdev Axes Swap (256):  0
        Axis Labels (257):      "Rel X" (129), "Rel Y" (130)
        Button Labels (258):    "Button Left" (122), "Button Middle" (123), "Button Right" (124), "Button Wheel Up" (125), "Button Wheel Down" (126), "Button Horiz Wheel Left" (127), "Button Horiz Wheel Right" (128), "Button Side" (245), "Button Extra" (246), "Button Forward" (560), "Button Back"
(561), "Button Task" (562), "Button Unknown" (239), "Button Unknown" (239), "Button Unknown" (239), "Button Unknown" (239)
        Evdev Middle Button Emulation (259):    2
        Evdev Middle Button Timeout (260):      50
        Evdev Wheel Emulation (261):    0
        Evdev Wheel Emulation Axes (262):       0, 0, 4, 5
        Evdev Wheel Emulation Inertia (263):    10
        Evdev Wheel Emulation Timeout (264):    200
        Evdev Wheel Emulation Button (265):     4
        Evdev Drag Lock Buttons (266):  0

No AngleOffset :-(.

Unfortunately the Trackball is unusable with the default settings,
so any helpful hint would be highly appreciated.


Regards

Harri
