当您插入任何USB 设备(USB Device)时，您是否收到以下消息“您连接到此计算机的最后一个USB设备出现故障， (USB)Windows无法识别它。” 设备管理器具有 Universal Serial Bus Controllers Flag USB Device Not Recognized。设备描述符请求(Device Descriptor Request)失败。
根据您的 PC，您将收到以下错误消息：
- Windows已停止此设备，因为它报告了问题。（代码 43 ）对(Code 43)USB设备描述符的请求失败。
- 您连接到这台计算机的最后一个USB设备出现故障，Windows无法识别它。”
- 连接到这台计算机的USB设备之一出现故障，Windows无法识别它。
- USBDEVICE_DESCRIPTOR_FAILURE
您应该检查的第一件事是您的 USB 驱动程序，如果驱动程序没有问题，然后检查USB 端口(USB Port)是否没有损坏。这可能是硬件问题，但如果您的其他设备工作正常，则不会是硬件问题。
问题是否仅在您插入特定设备（如硬盘）时出现？那么问题可能出在该特定设备上。检查设备是否在另一台 PC 或笔记本电脑上工作。如果该设备在另一台笔记本电脑上完美运行，那么主板(Motherboard)问题的可能性很小。但别担心，在您认为您的主板(Motherboard)出现故障之前，您可以尝试修复Windows 10中的(Windows 10)USB Device Descriptor Failure错误。
“无法识别(Recognized)USB 设备(USB Device)”背后的原因。设备描述符请求(Device Descriptor Request)失败”问题是快速启动(Fast Startup)或USB 选择性挂起设置(USB Selective Suspend Settings)。除了这两个之外，还有其他几个问题可能导致USB 设备(USB Device)无法识别(Recognized)错误。由于每个用户都有不同的设置和系统配置，您需要尝试所有列出的方法才能解决问题。因此，不要浪费任何时间，让我们看看如何修复无法(Fix USB Device)识别(Recognized)的 USB 设备。在下面列出的教程的帮助下，设备描述符请求失败。(Device Descriptor Request)

- The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.”
- One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.
- USB\DEVICE_DESCRIPTOR_FAILURE
The first thing you should check is your USB drivers if there is no problem with the drivers then check if the USB Port is not damaged. It might be a hardware problem but if your other devices are working fine then it can’t be a hardware problem.
Does the problem occur only when you insert a particular device such as a hard disk? Then the issue might be with that particular device. Check if the device is working on another PC or laptop. If the device works perfectly on another laptop then there is a slight chance that the problem might with the Motherboard. But don’t worry, before thinking that your Motherboard is malfunctioning there are a couple of fixes you could try to fix the USB Device Descriptor Failure error in Windows 10.
The cause behind the “USB Device Not Recognized. Device Descriptor Request Failed” issue is Fast Startup or USB Selective Suspend Settings. Apart from these two, there are several other issues that can lead to the USB Device Not Recognized error.
