Thanks for the report.

As Peter mentioned in the bug, there is a missing property on the kernel
node (INPUT_PROP_BUTTONPAD). 

The thing is this property is solely driven in the current driver by the
provided platform_data, so there is no way we ever set it through
hid-rmi. I wonder how we missed that.

Anyway, the good news is that the evemu record shows only one exportted
button, so we can infer the property quite easily in the module. Would
something like that work for you?
