Hi.........thanks for the info. Is the library node supposed to automatically configure the parameters?
How would you set up the parameters for this function. Using the setupAPI,dll
HDEVINFO
SetupDiGetClassDevs(
IN LPGUID ClassGuid, OPTIONAL
IN PCTSTR Enumerator, OPTIONAL
IN HWND hwndParent, OPTIONAL
IN DWORD Flags
);
see link http://msdn.microsoft.com/en-us/library/ms792959.aspx
The SetupDiGetClassDevs I believe is the first step to finding the USB devices There are more functions I need to call, but I need to get the first step done correctly. I wish there were some documentation out there that would clearly describe the dll's ,funtions of the dll's and the order in which to call them to find USB devices. The return value is connected to the DeviceInfoSet on the next funtion call.
SetupDiEnumDeviceInterfaces.
WINSETUPAPI BOOL WINAPI
SetupDiEnumDeviceInterfaces(
IN HDEVINFO DeviceInfoSet,
IN PSP_DEVINFO_DATA DeviceInfoData, OPTIONAL
IN LPGUID InterfaceClassGuid,
IN DWORD MemberIndex,
OUT PSP_DEVICE_INTERFACE_DATA DeviceInterfaceData
);

You help on this is greatly appriciated.
Thanks
