STM32F4 Discovery HID device - report desciptor

Question asked by mrv on Feb 22, 2016

I'm very new to STM32 family and I've been struggling for the past few days getting the HID device working the way I'd like it to.

Basically, I'd like to create a custom device which would send 4 float values (16 bytes) over to the PC, and I'm trying to modify the report descriptor from the demonstration example to do so, but no matter what I do, I always end up with 4 bytes only at the PC side. 

Could anyone experienced with HID be kind enough to write a set of changes I have to do to accomplish what I need?
