Hi Alexey,

I am wondering how this patch was tested, please? See comments below.

You are not adding a new switch case to holtek_mouse_report_fixup(), hence 
your patch seems to be a no-op (as the function does absolutely nothing 
and returns the original descriptor back)?

You also need to add the device to hid_have_special_driver[] so that the 
binding is guaranteed to be correct.

Could you please work in fixing up and resending the patch?

Thanks,
