USB控制器驱动注册表键名称DriverKeyName

使用IOCTL_GET_HCD_DRIVERKEY_NAME获取USB驱动注册表键值名称。

DriverKeyName是一个Windows驱动程序的注册表键名。在Windows操作系统中，驱动程序使用注册表来存储设备和驱动程序的相关信息。DriverKeyName指的是驱动程序在注册表中的键名，它通常用于标识驱动程序和设备之间的关联关系。通过DriverKeyName，操作系统可以查找并加载正确的驱动程序，以支持设备的正常工作。

请注意，具体的DriverKeyName的命名和结构可能会因驱动程序的不同而有所差异。它一般由厂商提供的驱动程序开发工具生成，并根据设备的硬件特性和功能进行命名。在注册表中，DriverKeyName通常位于HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\下，用于存储与设备相关的信息。

对于USB控制器，可以通过以下测试代码来获取

#include <iostream>
#include <windows.h>
#include <tchar.h>
#include <usbdi.h>

VOID UsbControlInfo(HANDLE h)
{
    char buff[1024] = { 0 };
    ULONG rtn = 0;
    BOOL isok = DeviceIoControl(h, IOCTL_GET_HCD_DRIVERKEY_NAME, NULL, 0, buff, sizeof(buff), &rtn, NULL);
    if (isok)
    {
        PUSB_HCD_DRIVERKEY_NAME pInfo = (PUSB_HCD_DRIVERKEY_NAME)buff;
        printf("%ws\n", pInfo->DriverKeyName);
    }
}

#define NUM_HCS_TO_CHECK 10
VOID EnumerateHostControllers()
{
    TCHAR        HCName[16];
    for (int HCNum = 0; HCNum < NUM_HCS_TO_CHECK; HCNum++)
    {
        _stprintf_s(HCName, sizeof(HCName) / sizeof(HCName[0]), _T("\\\\.\\HCD%d"), HCNum);
        HANDLE hHCDev = CreateFile(HCName,
            GENERIC_WRITE,
            FILE_SHARE_WRITE,
            NULL,
            OPEN_EXISTING,
            0,
            NULL);
        if (hHCDev != INVALID_HANDLE_VALUE)
        {
            UsbControlInfo(hHCDev);
            CloseHandle(hHCDev);
        }
    }
}
int main()
{
    EnumerateHostControllers();
    return 0;
}

在本人电脑中输出为：

{36fc9e60-c465-11cf-8056-444553540000}\0002
{4d36e97d-e325-11ce-bfc1-08002be10318}\0071

而以上2个正对对应本人电脑中2个USB控制器的驱动键名:
