+I've had problems with mice which are too severe and I can't easily control 
+them (probably not your problem though). The solution was to install the 
+xinput rpm, then do an "xinput list" to find out the name of your mouse:-
+
+[derij at pip ~]$ xinput list
+â¡ Virtual core pointer                         id=2    [master pointer  (3)]
+â   â³ Virtual core XTEST pointer               id=4    [slave  pointer  (2)]
+â   â³ Stylus1                                  id=6    [slave  pointer  (2)]
+â   â³ Eraser1                                  id=7    [slave  pointer  (2)]
+â   â³ Cursor1                                  id=8    [slave  pointer  (2)]
+â   â³ Pad1                                     id=9    [slave  pointer  (2)]
+â   â³ USB Optical Mouse                        id=15   [slave  pointer  (2)]
+â£ Virtual core keyboard                        id=3    [master keyboard (2)]
+    â³ Virtual core XTEST keyboard              id=5    [slave  keyboard (3)]
+    â³ Power Button                             id=10   [slave  keyboard (3)]
+    â³ Power Button                             id=11   [slave  keyboard (3)]
+    â³ NOVATEK USB Keyboard                     id=13   [slave  keyboard (3)]
+    â³ NOVATEK USB Keyboard                     id=14   [slave  keyboard (3)]
+    â³ em28xx IR (em28xx #0)                    id=12   [slave  keyboard (3)]

+And use the name in a command to set one of the properties, in my case  
+"Device Accel Constant Deceleration".
+
+xinput set-prop 'USB Optical Mouse' --type=float "Device Accel Constant 
+Deceleration" 2.4
+
+There are many other properties which can be set:-
+
+[derij at pip ~]$ xinput list-props "USB Optical Mouse"
+Device 'USB Optical Mouse':
+        Device Enabled (125):   1
+        Coordinate Transformation Matrix (127): 1.000000, 0.000000, 0.000000, 
+0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
+        Device Accel Profile (244):     0
+        Device Accel Constant Deceleration (245):       2.400000
+        Device Accel Adaptive Deceleration (246):       1.000000
+        Device Accel Velocity Scaling (247):    10.000000
+        Device Product ID (268):        6447, 1046
+        Device Node (254):      "/dev/input/event17"
+        Evdev Axis Inversion (298):     0, 0
+        Evdev Axes Swap (300):  0
+        Axis Labels (301):      "Rel X" (135), "Rel Y" (136)
+        Button Labels (302):    "Button Left" (128), "Button Middle" (129), 
+"Button Right" (130), "Button Wheel Up" (131), "Button Wheel Down" (132), 
+"Button Horiz Wheel Left" (133), "Button Horiz Wheel Right" (134)
+        Evdev Middle Button Emulation (286):    0
+        Evdev Middle Button Timeout (287):      50
+        Evdev Third Button Emulation (288):     0
+        Evdev Third Button Emulation Timeout (289):     1000
+        Evdev Third Button Emulation Button (290):      3
+        Evdev Third Button Emulation Threshold (291):   20
+        Evdev Wheel Emulation (292):    0
+        Evdev Wheel Emulation Axes (293):       0, 0, 4, 5
+        Evdev Wheel Emulation Inertia (294):    10
+        Evdev Wheel Emulation Timeout (295):    200
+        Evdev Wheel Emulation Button (296):     4
+        Evdev Drag Lock Buttons (297):  0
+
+See if any make the mouse usage easier. I put my custom settings in a file 
+which gets run during KDE startup. I also have the script on the desktop since 
+if the USB mouse becomes detached the settings go back to the defaults.
