Get device interface from SetupDiGetClassDevs

Question

is it possible to somehow get interface string for using with CreateFile from SetupDiGetClassDevs function or related functions? I have to scan for my devices connected to computer.

Answer 1

For each device returned from SetupDiGetClassDevs, you need to enumerate device interfaces using SetupDiEnumDeviceInterfaces, and then retrieve detail data using SetupDiGetDeviceInterfaceDetail. The SP_DEVICE_INTERFACE_DETAIL_DATA structure filled in by SetupDiGetDeviceInterfaceDetail contains the correct CreateFile path.
