I am thinking you have the MP21ZP? Looks like it should have some parameters you can set to adjust the reporting. The driver may not expose them but they can be set manually.

You can use this driver to set any parameters you want (switch to it then switch back when done)
If you need more explanation just let us know, someone can explain it further I'm sure.
