Evdev 1.1.2:

Using evdev with the following configuration:

> Section "InputDevice"
>         Identifier      "Mouse0"
>         Driver          "evdev"
>         Option          "Dev Name"              "Logitech USB RECEIVER" # cat
/proc/bus/input/devices
> EndSection

Produces the following error on my system:

> (II) evdev brain: Rescanning devices (1).
> (**) Option "CorePointer"
> (**) Mouse0-isa0061/input0: Core Pointer
> (EE) Mouse0-isa0061/input0: Don't know how to use device.
