I've recently implemented RawInput in my engine, and I'm using the HID functions to query the devices on the system. When I call GetRawInputBuffer and start parsing RAWINPUT packets to HID devices, I can differentiate them by the HANDLE in the RAWINPUT header.

But I can't find a way to tie this HANDLE to anything returned by the HID functions (HidD_GetPreparsedData etc.) I can get the same HANDLE by calling GetRawInputDeviceList, but I still don't have all the extra information provided by the HID functions (product name, calibration data, etc.)

That's very much appreciated! I think I figured it out though, I have to use GetRawInputDeviceInfo with RIDI_DEVICENAME to get the device path to open with CreateFile. I was getting it with SetupDiGetDeviceInterfaceDetail before, but this way I have the same HANDLE that will come in with the RAWINPUT packets.

Thanks for the reply!
