This is a rather unusual device.  Is this really the way power
devices are supposed to work?

Anyway, perhaps there should be a way not to make a separate
uhid device for each report id.  This is the way it used to
be (but that doesn't work for devices where only the report
id distinguishes a mouse from a keyboard).
I suggest using 'flag 1' on the uhidev device.
