interface ! 

DEFINE_GUID(IID_IDirectInputDevice8A,0x54D41080,0xDC15,0x4833,0xA4,0x1B,0x74,0x8F,0x73,0xA3,0x81,0x79);

So it's trying to get the interface to a Device8A object.

Could you try changing the dlls/dinput/device.c file in the function
'IDirectInputDevice2AImpl_QueryInterface' adding the part with the '+' in front:

    if (IsEqualGUID(&IID_IDirectInputDevice7A,riid)) {
	IDirectInputDevice7_AddRef(iface);
	*ppobj = This;
	return DI_OK;
    }
+    if (IsEqualGUID(&IID_IDirectInputDevice7A,riid)) {
+	IDirectInputDevice7_AddRef(iface);
+	*ppobj = This;
+	return DI_OK;
+    }
    TRACE("Unsupported interface !\n");
    return E_FAIL;
