Windows成功加载了此硬件的设备驱动程序，但找不到硬件设备（代码 41^{(Code 41)}）

如果您遇到这种情况，您可以尝试以下我们推荐的解决方案（不分先后顺序），看看这是否有助于解决问题。

1. 编辑注册表项
2. 卸载并重新安装设备
3. 手动更新设备驱动程序

让我们看一下关于列出的每个解决方案所涉及的过程的描述。

1]编辑注册表项

由于这是注册表操作，建议您备份注册表^{(back up the registry)} 或 创建系统还原点 作为必要的预防措施。完成后，您可以执行以下操作：

• 按Windows key + R调用“运行”对话框。
• 在“运行”对话框中，键入regedit并按 Enter 以打开注册表编辑器^{(open Registry Editor)}。
• 导航或跳转到下面的注册表项路径：

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4d36e965-e325-11ce-bfc1-08002be10318}

• 在该位置的右窗格中，右键单击并删除UpperFilters和LowerFilters条目。
• 重启你的电脑。

如果该位置不存在条目，您可以跳到下一个解决方案。

2]卸载^(Uninstall)并重新安装设备

请执行下列操作：

• 按 Windows key + X 打开 高级用户菜单^{(Power User Menu)}。
• 点击 键盘上的M 键 打开设备管理器^{(open Device Manager)}。
• 设备管理器^{(Device Manager)}打开后，识别有问题的设备（通常带有黄色感叹号）并右键单击它。
• 从上下文菜单中单击卸载设备。^{(Uninstall device )}
• 在确认消息提示上单击确定。^{( OK)}
• 卸载完成后，将光标移动到菜单栏并单击Action。
• 然后，单击 扫描硬件更改^{(Scan for hardware changes)} 并等待该过程完成。

Windows 10 将自动检测硬件并将其安装在您的计算机上。

• 重新启动^(Reboot)计算机以使更改生效。

现在应该解决该错误。

3 ]手动^{(] Manually)}更新设备驱动程序

此解决方案要求您通过设备管理器手动更新驱动程序^{(update your drivers manually via the Device Manager)}，或者您可以 在Windows Update下^{(Windows Update)}的可选更新^{(get the driver updates on the Optional Updates)}部分获取驱动程序更新。您可以 从制造商的网站下载有问题的设备驱动程序的最新版本。^{(download the latest version of the problematic device driver)}

希望这可以帮助！

If you’re faced with this, you can try our recommended solutions below in no particular order and see if that helps to resolve the issue.

1. Edit registry entry
2. Uninstall and reinstall the device
3. Manually update the device driver

Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Edit registry entry

Since this is a registry operation, it is recommended that you back up the registry or create a system restore point as necessary precautionary measures. Once done, you can proceed as follows:

• Press Windows key + R to invoke the Run dialog.
• In the Run dialog box, type regeditand hit Enter to open Registry Editor.
• Navigate or jump to the registry key path below:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4d36e965-e325-11ce-bfc1-08002be10318}

• At the location, on the right pane, right-click and delete both the UpperFilters and LowerFilters entry.
• Restart your computer.

If the entries are not present in that location, you can skip to the next solution.

2] Uninstall and reinstall the device

Do the following:

• Press Windows key + X to open the Power User Menu.
• Tap M key on the keyboard to open Device Manager.
• Once the Device Manager opens, identify the problematic device (usually having a yellow exclamation mark) and right-click on it.
• Click on Uninstall device from the context menu.
• Click OK on the confirmation message prompt.
• When the un-installation finishes, move your cursor to the menu bar and click on Action.
• Then, click on Scan for hardware changes and wait for the process to complete.

Windows 10 will automatically detect the hardware and install it on your computer.

• Reboot your computer for the changes to take effect.

The error should now be resolved.

3] Manually update the device driver

This solution requires you to either update your drivers manually via the Device Manager, or you can get the driver updates on the Optional Updates section under Windows Update. You can download the latest version of the problematic device driver from the manufacturer’s website.

Hope this helps!
