Good questions, it seems like microsoft is not distributing the idl,
only tlb and dll files.
However I have the same problem with DSF.HotPlug not accepting
DSFDevice objects. And for DSF the idl is available:
interface IDSF : IDispatch
{
...
HRESULT _stdcall HotPlug ([in] DSFDevice *pDSFDevice,
[in] BSTR bstrBus,
[out, retval] IDSFBus **ppiDSFBus);
...
};
interface IDSFDevice : IDispatch
{
...
};
coclass DSFDevice
{
[default] interface IDSFDevice;
[default, source] interface IDSFDeviceEvents;
};
again,
import comtypes.client as cc
dsf = cc.CreateObject("DSF.DSF")
mydev = cc.CreateObject("DSF.DSFDevice")
dsf.HotPlug(mydev, "USB2.0") # throws TypeError
comtypes generated code:
IDSF._methods_ = [
...
COMMETHOD([dispid(1248), helpstring(u'Plugs the given DSFDevice
into the bus which is defined eithe by its GUID or friendly name.')],
HRESULT, 'HotPlug',
( ['in'], POINTER(DSFDevice), 'pDSFDevice' ),
( ['in'], BSTR, 'bstrBus' ),
( ['retval', 'out'], POINTER(POINTER(IDSFBus)), 'ppiDSFBus' )),
]
changing that ( ['in'], POINTER(DSFDevice) to ( ['in'],
POINTER(IDSFDevice) solves the problem
