有人可以看看我做得对吗请:

我的SetupDiEnumDeviceInterfaces(在GetDevice()函数中)没有做任何事情.它甚至没有进入while循环...有人可以试着指出我做错了什么吗？
谢谢
编辑/更多信息:我刚刚调用了GetLastError()函数,它返回了一个259 - ERROR_NO_MORE_ITEMS.设备甚至可能不包含接口吗？
跟上这个吧.
我试图尽可能少地破解你的原始代码; 以下代码(至少对我来说)通过内部while(SetupDiEnumDeviceInterfaces..):
void DeviceManager::GetDeviceUSB(std::string vid, std::string pid)
{
DWORD deviceIndex = 0;
deviceInfoData.cbSize = sizeof(deviceInfoData);
//buried somewhere deep in the ddk
static GUID GUID_DEVINTERFACE_USB_HUB={ 0xf18a0e88, 0xc30c, 0x11d0, {0x88, 0x15, 0x00, 0xa0, 0xc9, 0x06, 0xbe, 0xd8} };
static GUID GUID_DEVINTERFACE_USB_DEVICE ={ 0xA5DCBF10L, 0x6530, 0x11D2, { 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0xED } };
static GUID GUID_DEVINTERFACE_USB_HOST_CONTROLLER={ 0x3abf6f2d, 0x71c4, 0x462a, {0x8a, 0x92, 0x1e, 0x68, 0x61, 0xe6, 0xaf, 0x27}};
//get usb device interfaces
HDEVINFO deviceInterfaceSet=SetupDiGetClassDevs(&GUID_DEVINTERFACE_USB_DEVICE, NULL, NULL, DIGCF_DEVICEINTERFACE);
while(SetupDiEnumDeviceInfo(deviceInterfaceSet, deviceIndex, &deviceInfoData))
{
deviceInfoData.cbSize = sizeof(deviceInfoData);
ULONG IDSize;
CM_Get_Device_ID_Size(&IDSize, deviceInfoData.DevInst, 0);
TCHAR* deviceID = new TCHAR[IDSize];
CM_Get_Device_ID(deviceInfoData.DevInst, deviceID, MAX_PATH, 0);
if( deviceID[8]==vid.at(0) && deviceID[9]==vid.at(1) && deviceID[10]==vid.at(2) && deviceID[11]==vid.at(3) && //VID
deviceID[17]==pid.at(0) && deviceID[18]==pid.at(1) && deviceID[19]==pid.at(2) && deviceID[20]==pid.at(3)) //PID
{
DWORD deviceInterfaceIndex = 0;
deviceInterfaceData.cbSize = sizeof(deviceInterfaceData);
while(SetupDiEnumDeviceInterfaces(deviceInterfaceSet, &deviceInfoData, &GUID_DEVINTERFACE_USB_DEVICE, deviceInterfaceIndex, &deviceInterfaceData))
{
deviceInterfaceData.cbSize = sizeof(deviceInterfaceData);
std::cout << deviceInterfaceIndex << std::endl;
//get some more details etc
//DWORD requiredBufferSize;
//SetupDiGetDeviceInterfaceDetail(deviceInterfaceSet, &deviceInterfaceData, NULL, 0, &requiredBufferSize,
deviceInterfaceIndex++;
}
}
deviceIndex++;
}
}
afaik,这个方法选择与你的OP构造函数调用相同的设备:(
注意:我包括一些其他有用的接口guids)
deviceInfoSet = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES); //Gets all Devices
但我这样做是为了获得设备接口:
// /coughs/ you might want to put back the DIGCF_PRESENT flag i removed for testing
HDEVINFO deviceInterfaceSet=SetupDiGetClassDevs(&GUID_DEVINTERFACE_USB_DEVICE, NULL, NULL, DIGCF_DEVICEINTERFACE);
我还传递deviceInfoData到SetupDiEnumDeviceInterfaces根据文档因为:
指向SP_DEVINFO_DATA结构的指针,该结构指定DeviceInfoSet中的设备信息元素.此参数是可选的,可以为NULL.如果指定了此参数,则SetupDiEnumDeviceInterfaces会将枚举限制为指定设备支持的接口.如果此参数为NULL,则重复调用SetupDiEnumDeviceInterfaces将返回有关与DeviceInfoSet中所有设备信息元素关联的接口的信息.此指针通常由SetupDiEnumDeviceInfo返回.
从设备安装类文档:
设备安装程序类定义了安装设备所涉及的类安装程序和类共同安装程序
从设备接口类文档:
设备接口类是将设备和驱动程序功能导出到其他系统组件(包括其他驱动程序)以及用户模式应用程序的一种方法
所以:
deviceInfoSet = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL,DIGCF_PRESENT|DIGCF_ALLCLASSES);
这是检索所有设置类信息集并过滤"USB"
你可以这样做:
deviceInfoSet = SetupDiGetClassDevs(NULL, NULL, NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES|DIGCF_DEVICEINTERFACE);`
这将检索支持任何类的设备接口的设备的类信息集.(应用一个emumerator ID s/a"USB"似乎没有影响)但至关重要:The function adds to the device information set a device information element that represents such a device and then adds to the device information element a device interface list that contains all the device interfaces that the device supports.
(及注意事项: SP_DEVINFO_DATA.ClassGuid是永远设备的的GUID 设置类)
Afaik:
但是你仍然需要InterfaceClassGuid在调用时提供〜tbh SetupDiEnumDeviceInterfaces()
,我真的不明白为什么在调用者提供可选项时这是必要的,DeviceInfoData
但由于它是所有封闭源,我怎么知道!:)
&这是关于GUID_DEVINTERFACE_USB_DEVICE的信息
(;免责声明:我不为M $工作;请怀疑地对待上述信息:) &&当然是dyoRs;)
希望这有帮助,祝你好运!
