Can I use SetupDiEnumDeviceInterfaces to get a DevicePath from SetupDiGetDeviceInterfaceDetail when no InterfaceClassGUID is known?
No, you cannot use SetupDiEnumDeviceInterfaces
to retrieve a DevicePath from SetupDiGetDeviceInterfaceDetail
without knowing the InterfaceClassGUID
. The SetupDiEnumDeviceInterfaces
function requires the InterfaceClassGUID
parameter to enumerate device interfaces.
The SetupDiEnumDeviceInterfaces
function is used to enumerate the device interfaces that are associated with a specified device information set and a device interface class. It requires the InterfaceClassGUID
parameter to identify the specific class of interfaces you want to enumerate.
On the other hand, SetupDiGetDeviceInterfaceDetail
retrieves details about a device interface from a device information set. To use this function, you need to provide the InterfaceClassGUID
along with other parameters.
If you don't know the InterfaceClassGUID
, you will need to obtain it or have some other identifying information about the device to correctly call these functions. Usually, you would have to identify the device by its InterfaceClassGUID
or other device-related information before using SetupDiEnumDeviceInterfaces
and SetupDiGetDeviceInterfaceDetail
.
It's important to note that the InterfaceClassGUID
uniquely identifies a particular device interface class, and it is essential to have this information to correctly interact with device interfaces using the Windows SetupAPI functions.
