不使用 Windows 驱动程序工具包列出具有指定 VID 和 PID 的 USB 设备 [英] list USB device with specified VID and PID without using Windows driver Kit

问题描述

有没有办法在不涉及调用 WDK 函数的情况下在 Windows 上找到具有指定 VID 和 PID 的 USB 设备?

is there a way to find a USB device with specified VID and PID on windows without involve calling to WDK functions?

推荐答案

下面的代码可以解决问题:

The code below will do the trick:

static const char dongleVid[] = {'1', '2', '3', '4', '\0'};
static const char donglePid[] = {'5', '6', '7', '8', '\0'};
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,
                                          sizeof(szDesc),   // The size, in bytes
                                          &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('\0');
    szPid[0] = TEXT('\0');
    szMi[0] = TEXT('\0');
    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));
    std::string foundPid = boost::to_upper_copy(std::string(szPid));

    if (requiredVid == foundVid && requiredPid == foundPid)
    {
        return true;
    }
}
