If you install the KB4524147, it may cause removable USB controller broken.

Translated by Google Translate.

All of my external USB devices failed after I went to work today. The result of the final check was that the Intel USB 3.1 XHCI Controller on the ThinkPad Thunderbolt 3 Dock Gen 2 failed. The error message is Object Name already exists. Code 31. Then I repeatedly removed the device and then did a hardware change scan several times. There was no way to solve this problem, then I started my debugging process.

First of all, I removed the KB4524147 first, then it didn't work after rebooting. I also did several removals and hardware change scans. It didn't work, so I started to remove all the software related to Thunderbolt, from the software with the latest installation date. After I started the removal, and after the reboot, I started to update the latest major and recommended firmware and drivers with Lenovo Vantage, and all UEFI / Thunderbolt / Intel ME Firmwares were updated.

After plugging in the ThinkPad Thunderbolt 3 Dock Gen 2, the above Intel USB 3.1 XHCI Controller is still in a failed state. I came to think of one thing. I recently tested the VirtualHere USB Server function, so I installed VirtualHere USB Controller on my computer. I guess I probably have this problem left. After I removed all the Intel USB 3.1 XHCI Controller with the exclamation mark and the VirtualHere USB 3 XHCI Controller, after the hardware change scan, the Intel USB 3.1 XHCI Controller function on the ThinkPad Thunderbolt 3 Dock Gen 2 returned to normal.

So the war criminals are KB4524147 and VirtualHere USB 3 XHCI Controller, the victim is the Intel USB 3.1 XHCI Controller on the ThinkPad Thunderbolt 3 Dock Gen 2, and then I am the unfortunate lightning rod that Google can't find the result.

中文原文：

今天上班的時候我所有外接的 USB 裝置都失效了，最後檢查的結果是 ThinkPad Thunderbolt 3 Dock Gen 2 上面的 Intel USB 3.1 XHCI Controller 失效，錯誤訊息是 Object Name already exists. Code 31。然後我重複移除裝置，然後做硬體變更掃描好幾次，這個問題都沒有辦法解決，然後我開始了我的除錯過程。

首先我先移除 KB4524147，然後重新開機之後沒有用，也做過多次的移除裝置跟硬體變更掃描，也沒有用，所以我開始移除所有跟 Thunderbolt 相關的軟體，從安裝日期最近的軟體開始移除，然後經歷過重開機之後，我開始用 Lenovo Vantage 更新最近的重大跟建議等級的韌體跟驅動程式，連 UEFI / Thunderbolt / Intel ME Firmware 都全部更新了。

最後插上 ThinkPad Thunderbolt 3 Dock Gen 2 後，上面的 Intel USB 3.1 XHCI Controller 還是失效狀態，再來我想到一件事情，我最近在測試 VirtualHere USB Server 的功能，所以我的電腦上面有安裝 VirtualHere USB Controller，我猜想大概就剩下這個問題了。我索性把所有顯示驚嘆號的 Intel USB 3.1 XHCI Controller 跟 VirtualHere USB 3 XHCI Controller 移除之後，做硬體變更掃描之後，ThinkPad Thunderbolt 3 Dock Gen 2 上面的 Intel USB 3.1 XHCI Controller 功能就恢復正常了。

所以戰犯是 KB4524147 跟 VirtualHere USB 3 XHCI Controller，受害人是 ThinkPad Thunderbolt 3 Dock Gen 2 上面的 Intel USB 3.1 XHCI Controller，然後我是那個 Google 找不到結果的不幸避雷針。
