列出指定VID和PID的USB设备,不使用Windows驱动程序工具包



是否有办法在windows上找到具有指定VID和PID的USB设备,而不涉及调用WDK函数?

以下是郭彦超代码的简化版本:

unsigned index;
HDEVINFO hDevInfo;
SP_DEVINFO_DATA DeviceInfoData;
TCHAR HardwareID[1024];
// List all connected USB devices
hDevInfo = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL, DIGCF_PRESENT | DIGCF_ALLCLASSES);
for (index = 0; ; index++) {
    DeviceInfoData.cbSize = sizeof(DeviceInfoData);
    if (!SetupDiEnumDeviceInfo(hDevInfo, index, &DeviceInfoData)) {
        return false;     // no match
    }
    SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_HARDWAREID, NULL, (BYTE*)HardwareID, sizeof(HardwareID), NULL);
    if (_tcsstr(HardwareID, _T("VID_1234&PID_5678"))) {
        return true;     // match
    }
}

下面的代码可以达到这个效果:

static const char dongleVid[] = {'1', '2', '3', '4', ''};
static const char donglePid[] = {'5', '6', '7', '8', ''};
static const LPCTSTR arPrefix[3] = {TEXT("VID_"), TEXT("PID_"), TEXT("MI_")};
const std::string requiredVid = boost::to_upper_copy(std::string(arPrefix[0]) + std::string(dongleVid));
const std::string requiredPid = boost::to_upper_copy(std::string(arPrefix[1]) + std::string(donglePid));
unsigned i, j;
DWORD dwSize, dwPropertyRegDataType;
OSVERSIONINFO osvi;
CONFIGRET r;
HDEVINFO hDevInfo;
SP_DEVINFO_DATA DeviceInfoData;
TCHAR szDeviceInstanceID[MAX_DEVICE_ID_LEN];
TCHAR szDesc[1024];
LPTSTR pszToken, pszNextToken;
TCHAR szVid[MAX_DEVICE_ID_LEN], szPid[MAX_DEVICE_ID_LEN], szMi[MAX_DEVICE_ID_LEN];
#ifdef UNICODE
FN_SetupDiGetDeviceProperty fn_SetupDiGetDeviceProperty = (FN_SetupDiGetDeviceProperty)
    GetProcAddress(GetModuleHandle(TEXT("Setupapi.dll")), "SetupDiGetDevicePropertyW");
#else
FN_SetupDiGetDeviceProperty fn_SetupDiGetDeviceProperty = (FN_SetupDiGetDeviceProperty)
    GetProcAddress(GetModuleHandle(TEXT("Setupapi.dll")), "SetupDiGetDevicePropertyA");
#endif
// List all connected USB devices
hDevInfo = SetupDiGetClassDevs(NULL, TEXT("USB"), NULL, DIGCF_PRESENT|DIGCF_ALLCLASSES);
if (hDevInfo == INVALID_HANDLE_VALUE)
{
    return false;
}
// Find the ones that are driverless
for (i = 0; ; i++)
{
    DeviceInfoData.cbSize = sizeof(DeviceInfoData);
    if (!SetupDiEnumDeviceInfo(hDevInfo, i, &DeviceInfoData))
    {
        break;
    }
    r = CM_Get_Device_ID(DeviceInfoData.DevInst, szDeviceInstanceID , MAX_PATH, 0);
    if (r != CR_SUCCESS)
    {
        continue;
    }
    SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData, SPDRP_DEVICEDESC,
                                          &dwPropertyRegDataType, (BYTE*)szDesc,

                                          &dwSize);
    // Retreive the device description as reported by the device itself
    memset(&osvi, 0, sizeof(OSVERSIONINFO));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
    pszToken = _tcstok_s(szDeviceInstanceID , TEXT("\#&"), &pszNextToken);
    szVid[0] = TEXT('');
    szPid[0] = TEXT('');
    szMi[0] = TEXT('');
    while (pszToken != NULL)
    {
        for (j = 0; j < 3; j++)
        {
            if (_tcsncmp(pszToken, arPrefix[j], lstrlen(arPrefix[j])) == 0)
            {
                switch (j)
                {
                    case 0:
                        _tcscpy_s(szVid, ARRAY_SIZE(szVid), pszToken);
                        break;
                    case 1:
                        _tcscpy_s(szPid, ARRAY_SIZE(szPid), pszToken);
                        break;
                    case 2:
                        _tcscpy_s(szMi, ARRAY_SIZE(szMi), pszToken);
                        break;
                    default:
                        break;
                }
            }
        }
        pszToken = _tcstok_s(NULL, TEXT("\#&"), &pszNextToken);
    }

    std::string foundVid = boost::to_upper_copy(std::string(szVid));

是的,你可以,你有所有必要的Win32 API在user32.dll和setuapi.dll。这是一个小小的c#示例:

internal static bool FindUsbDevice(string vendorId, string productId, 
        ref string deviceDesc, ref string deviceInstanceId, ref Guid classId)
    {
        bool returnValue = false;
        string enumeratorClass = "USB";
        IntPtr szClass = Marshal.StringToHGlobalAuto(enumeratorClass);
        Guid classGuid = Guid.Empty;
        IntPtr deviceInfoSet = new System.IntPtr();
        try
        {
            deviceInfoSet = DeviceManagement.SetupDiGetClassDevs(ref classGuid, szClass, IntPtr.Zero,
                DeviceManagement.DIGCF_ALLCLASSES | DeviceManagement.DIGCF_PRESENT);
            DeviceManagement.SP_DEVINFO_DATA spDevInfoData = new DeviceManagement.SP_DEVINFO_DATA();
            spDevInfoData.cbSize = Marshal.SizeOf(spDevInfoData);
            for (int i = 0; DeviceManagement.SetupDiEnumDeviceInfo(deviceInfoSet, i, ref spDevInfoData); i++)
            {
                int nSize = 0;
                string DeviceInstanceId = new string('0', 259);
                IntPtr ptrDeviceInstanceId = Marshal.StringToHGlobalAuto(DeviceInstanceId);
                if (!DeviceManagement.SetupDiGetDeviceInstanceId(deviceInfoSet, ref spDevInfoData, ptrDeviceInstanceId,
                    DeviceInstanceId.Length, ref nSize))
                {
                    Console.WriteLine("SetupDiGetDeviceInstanceId() error");
                    continue;
                }
                DeviceInstanceId = Marshal.PtrToStringAnsi(ptrDeviceInstanceId);
                if (!DeviceInstanceId.Contains(string.Format("USB\VID_{0}&PID_{1}", vendorId, productId)))
                    continue;
                returnValue = true;
                deviceInstanceId = DeviceInstanceId;
                classId = spDevInfoData.ClassGuid;
                int DataT = 0;
                string buffer = new string('0', 259);
                IntPtr pBuffer = Marshal.StringToHGlobalAuto(buffer);
                int bufferSize = 259;
                if (!DeviceManagement.SetupDiGetDeviceRegistryProperty(
                    deviceInfoSet, ref spDevInfoData, DeviceManagement.SPDRP_DEVICEDESC,
                    ref DataT, pBuffer, bufferSize, ref bufferSize))
                {
                    if (Marshal.GetLastWin32Error() == DeviceManagement.ERROR_INVALID_DATA)
                        Debug.WriteLine("Error invalid data");
                    else
                        Debug.WriteLine("error");
                }
                else
                {
                    buffer = Marshal.PtrToStringAnsi(pBuffer, bufferSize);
                    deviceDesc = buffer;
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            DeviceManagement.SetupDiDestroyDeviceInfoList(deviceInfoSet);
        }
        return returnValue;
    }
