No more warnings and oopses, so:

FTR, it now looks like this:
gusiac:/sys/bus/hid/devices/0003:046D:C50E.0004/input/input15 # ls -1 | 
grep input15
input15::charging
input15::mail
input15::misc

All three have max_brightness of 1, but echo 1 > brightness does 
nothing. Clearly the leds are indeed autonomous only and the mouse 
shouldn't even report them.

Thanks,
