it's not quite detected correctly, looking at the axis labels this device
looks like a standard USB mouse (two relative axes, one wheel, three
buttons).

for evdev/synaptics to treat this properly, the device needs ABS_X/Y and
BTN_TOOL_FINGER.

so really, you need to add support for this device to the kernel drivers.
