Mouse accel scaling wrong for hidpi display

On a Dell XPS 15 Touch laptop with a hidpi display running Fedora 20, when I plug in a mouse with device id 045e:0039, "Microsoft Corp. IntelliMouse Optical", the mouse pointer barely moves when the mouse is moved.
The default velocity and acceleration settings when the mouse is plugged in are:
Device Accel Constant Deceleration (263): 1000.000000 Device Accel Adaptive Deceleration (264): 1.000000 Device Accel Velocity Scaling (265): 1.000000
The following commands make the mouse usable:
xinput --set-prop "Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)" "Device Accel Constant Deceleration" 1.5 xinput --set-prop "Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)" "Device Accel Velocity Scaling" 250
It would be nice if these defaults were set automatically.
