I am a .dll that act as interface with my HID device and Windows API.
I am a problem to open a connection with my device using the CLFN. But if i run the example, that is made with VC++, that is provided from the Author of the .dll, the function return me the error code: "Device not Found"
The function and prototype in the DLL is:
FT260_STATUSFT260_OpenByVidPid(WORD vid, WORD pid, DWORD deviceIndex, FT260_HANDLE* pFt260Handle)
FT260_STATUS is an enum that i defined it as uint8 enum in labview

Hello,
I am a .dll that act as interface with my HID device and Windows API.
I am a problem to open a connection with my device using the CLFN. But if i run the example, that is made with VC++, that is provided from the Author of the .dll, the function return me the error code: "Device not Found"
The function and prototype in the DLL is:
FT260_STATUS FT260_OpenByVidPid(WORD vid, WORD pid, DWORD deviceIndex, FT260_HANDLE* pFt260Handle)
FT260_STATUS is an enum that i defined it as uint8 enum in labview
This is how I configured the CLFN:
uint8_t FT260_OpenByVidPid@16(uint16_t Vid, uint16_t Pid, uint32_t DeviceIndex, uint32_t* SessionID)
Convenction call is: stdcall (WINAPI)
Can someone help me to understand what is the problem?
Thank you very much
