I am trying to develop an API to detect if a USB device has been connected to my USB port. I am using MAX3420e as my USB device which is controlled through a MSP430 uC. I have little to zero knowledge of VC++, and I have been reading USB complete which mentions a sample code on how to detect a USB device and the functions associated with it... I have written a small code which would look for the PID and VID of the connected USB devices... however, I am getting the following error:
error LNK2019: unresolved external symbol "bool __cdecl HidD_GetAttributes(void *,struct _HIDD_ATTRIBUTES *)" (?HidD_GetAttributes@@YA_NPAXPAU_HIDD_ATTRIBUTES@@@Z) referenced in function _wmain
can anyone please let me know where I would be going wrong?? thanks...

Put setupapi.lib
as additional dependacy in Linker input tab.
