Win11 不能自动识别即插即用USB设备

你好，贾斯珀。让我们尝试检查系统注册表中是否存在可能的问题。请按照以下说明操作：

按 Win + R，键入“regedit”，然后按 Enter 打开注册表编辑器。

导航到“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class”。

在“类”文件夹中，您将看到几个子文件夹（称为键）。通常与 USB 设备关联的密钥包括：

'{36FC9E60-C465-11CF-8056-444553540000}'（USB 总线控制器）

{{4D36E967-E325-11CE-BFC1-08002BE10318}'（磁盘驱动器）

“{4D36E980-E325-11CE-BFC1-08002BE10318}”（磁盘控制器）

“{4D36E978-E325-11CE-BFC1-08002BE10318}”（大容量存储控制器）

单击每个键，然后在右窗格中查找名为“UpperFilters”和“LowerFilters”的条目。如果找到这些条目，请右键单击每个条目，然后选择“删除”。

注意：删除注册表中的条目时要小心。确保仅删除指定键中的“UpperFilters”和“LowerFilters”条目。

删除“UpperFilters”和“LowerFilters”条目后，关闭注册表编辑器并重新启动计算机。

请尝试此操作，看看它是否解决了您的 USB 设备的问题。如果这不起作用，您可能需要考虑硬件问题或与 Windows 11 不兼容的可能性。如果您有任何其他问题或需要进一步的帮助，请告诉我。

Thank you so much for following up.

I think there might be some translation issues, so I would like to explain my problem further in English.

I have tried modifying the registry as per the method I found earlier on the internet, but the previous modifications were {4d36e96b-e325-11ce-bfc1-08002be10318} (class==Keyboard) and {4d36e96f-e325-11ce-bfc1-08002be10318} class==Mouse), which have UpperFliters values present. Then, I followed the tutorial and deleted the data in the values, but kept the blank values. However, after deleting the data in these two values, Windows could not recognise the mouse and keyboard at all, so I restored it. On my computer, the {36fc9e60-c465-11cf-8056-444553540000} (class===USB) item and subitems you are referring to don't contain values named "UpperFilters" or "LowerFilters" already. so I couldn't delete them.

Also, I haven't had any problems with my USB storage devices not being recognised, so I haven't changed the registries related to disks and storage controllers, could the registries related to disks affect the USB port recognising other types of devices?
