please see #224
I'm confident we need to do the same thing for HidD_SetOutputReport as well.

@slouken It seems, you missed to respond to this question

It looks like #224 was just pre-allocating the buffer. Were you referring to another change that made sure the buffer size matched feature_report_length? I think, but I'm not sure, that the feature_report_length is the wrong size in this case.

I mean that the buffer size has to be at least output_report_length bytes in size.
If user passes less data - logically it is not a proble, but WinAPI implementation is known to crash if bufer is too small.
The workaround (as in #224) is to pre-allocate buffer that is large-enough if needed.
