我正在学习KMDF驱动程序与UWP应用开发，尝试通过UWP应用与KMDF驱动程序通信，根据面向应用开发人员的硬件支持应用 (HSA) 步骤 - Windows drivers | Microsoft Docs实现了，但是对驱动和UWP进行了一些更新后，UWP访问KMDF驱动会发生异常(拒绝访问。(Exception from HRESULT:0x80070005))
我不知道是否是在对UWP应用和驱动的更新过程中修改了什么发生了错误，因此我重新编写了一个驱动程序及其对应的UWP应用，同样发生了这个异常，下面是关于驱动程序和UWP应用的部分配置。
我想知道是什么导致了这个问题，如何解决这个问题？
驱动程序添加接口与自定义功能：
WDFSTRING symbolicLinkString = NULL;
UNICODE_STRING symbolicLinkName = SymbolicName;//符号链接名称
DEVPROP_BOOLEAN isRestricted;
status = WdfDeviceCreateDeviceInterface(
Device,
(LPGUID)&GUID_DEVINTERFACE_HSADrvSample,//设备接口GUID
NULL); // Reference String
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\t[ERROR]WdfDeviceCreateDeviceInterface failed with errorcode:%x\n", status));
goto Error;
}
if (g_pIoSetDeviceInterfacePropertyData != NULL) {
status = WdfStringCreate(NULL,
WDF_NO_OBJECT_ATTRIBUTES,
&symbolicLinkString);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\t[ERROR]WdfStringCreate failed with errorcode:%x\n", status));
goto Error;
}
status = WdfDeviceRetrieveDeviceInterfaceString(
Device,
(LPGUID)&GUID_DEVINTERFACE_HSADrvSample,
NULL,
symbolicLinkString);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\t[ERROR]WdfDeviceRetrieveDeviceInterfaceString failed with errorcode:%x\n", status));
goto Error;
}
WdfStringGetUnicodeString(symbolicLinkString, &symbolicLinkName);
isRestricted = DEVPROP_TRUE;
status = g_pIoSetDeviceInterfacePropertyData(
&symbolicLinkName,
&DEVPKEY_DeviceInterface_Restricted,
0,
0,
DEVPROP_TYPE_BOOLEAN,
sizeof(isRestricted),
&isRestricted);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\t[ERROR]IoSetDeviceInterfacePropertyData failed with errorcode:%x\n", status));
goto Error;
}
#if defined(NTDDI_WIN10_RS2) && (NTDDI_VERSION >= NTDDI_WIN10_RS2)
static const wchar_t customCapabilities[] = L"ColinTest.HSADrvSample_2022051717171\0";//自定义功能名称
status = g_pIoSetDeviceInterfacePropertyData(&symbolicLinkName,
&DEVPKEY_DeviceInterface_UnrestrictedAppCapabilities,
0,
0,
DEVPROP_TYPE_STRING_LIST,
sizeof(customCapabilities),
(PVOID)&customCapabilities);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\t[ERROR]IoSetDeviceInterfacePropertyData failed with errorcode:%x\n", status));
goto Error;
}
#endif
WdfObjectDelete(symbolicLinkString);
}
Error:

UWP包应用清单添加自定义功能：

<uap4:CustomCapability Name="ColinTest.HSADrvSample_2022051717171"/>
</Capabilities>
UWP应用SCCD文件：

UWP调用：
var selector = CustomDevice.GetDeviceSelector(DeviceInterfaceGuid);
Note.Text = "选择器：" + selector;
var enumDevice = DeviceInformation.FindAllAsync(selector).AsTask();
Task.WaitAll(enumDevice);
Note.Text = "找到了" + enumDevice.Result.Count + "个设备";
