Help with HID Parsing functions

I am developing manufacturer specific HID devices. I have written the
device's firmware and can connect and communicate with an application without
using the HID parsing routiines. There are several input (8) and several
output (7) reports.

I am now expanding the PC software to use the HID parsing functions to allow
the software to easily adapt to different versions of the device software.
For most of the output reports I can call HidP_InitializeReportForID without
any errors. For a couple output reports this function returns with an error
indicating that the report does not exist. However, I am then able to use
the other parsing functions to set the data in the report.

Does anyone know why this function may be returning an error? Any help or
items to double check in the device would be greatly appreacited

What are the reports (keyboard and mouse reports can be funky because
the OS opens them exclusively)? Are the all in the same top-level
collection?

Yes, the reports are all in the same top-level collection. The reports are
currently located in usage page 0x91 (Arcade devices).
