中药处方识别诊断_如何在Windows中诊断“无法识别USB设备”错误
中药处方识别诊断
Windows is designed to be almost universal in its support of PC accessories, particularly USB-based add-ons like external hard drives, flash drives, game controllers, webcams, microphones, and other peripherals. Most things work out-of-the-box thanks to pre-loaded drivers, but occasionally a gadget will still give you the dreaded “USB device not recognized” error.
Windows在设计上几乎对PC附件(包括外部硬盘驱动器，闪存驱动器，游戏控制器，网络摄像头，麦克风和其他外围设备)基于USB的附件的支持几乎是通用的。 由于预先加载了驱动程序，因此大多数事情都可以立即使用，但有时小工具仍然会给您带来可怕的“无法识别USB设备”错误。
There are a lot of different ways that this problem can manifest, and unfortunately Windows still isn’t very good at actually telling users how to solve it. Here are the most common issues and—in at least some cases—how to fix them.
这个问题可以通过很多不同的方式表现出来，不幸的是Windows仍然不能很好地告诉用户如何解决它。 以下是最常见的问题，以及(至少在某些情况下)如何解决这些问题。
您可能会缺少该设备的驱动程序 (You Might Be Missing Drivers for the Device)
Starting with Windows Vista, the operating system loads thousands of generic and specific drivers at the time of its installation, and adds new drivers for detected hardware periodically through Windows Update. So if the gadget you’re plugging in to your computer is simple enough, or it comes from a major manufacturer like Logitech, it should work right away or after a quick, semi-automatic download.
从Windows Vista开始，操作系统在安装时会加载数千个通用驱动程序和特定驱动程序，并通过Windows Update定期为检测到的硬件添加新的驱动程序。 因此，如果您要插入计算机的小工具足够简单，或者它来自Logitech之类的主要制造商，那么它应该立即运行或在快速，半自动下载后才能正常工作。
If it doesn’t, it might mean that your device isn’t covered by Microsoft’s generic built-in drivers or the larger database of drivers on the Windows Update servers. That means you’ll need to download the necessary drivers from the manufacturer’s website.
如果没有，则可能意味着您的设备不受Microsoft的通用内置驱动程序或Windows Update服务器上更大的驱动程序数据库覆盖。 这意味着您需要从制造商的网站下载必要的驱动程序。
Most drivers should install just like any other Windows program. If that doesn’t work, though, read on.
大多数驱动程序应像安装其他Windows程序一样安装。 如果仍然无法解决问题，请继续阅读。
您的计算机可能使用了不正确或过时的驱动程序 (Your Computer Might Be Using Incorrect or Outdated Drivers)
As handy as Windows’ automatic driver detection is, it isn’t perfect. Sometimes it matches the wrong driver with the device, or the device hardware has been updated by the manufacturer to the point where the original driver is no longer applicable. If the installed drivers or ones downloaded from the manufacturer’s site on the web aren’t working, you’ll need to manually select the device and driver using Device Manager.
尽管Windows自动检测驱动程序很方便，但它并不完美。 有时，它将错误的驱动程序与设备匹配，或者制造商已将设备硬件更新到不再适用原始驱动程序的程度。 如果已安装的驱动程序或从网络上的制造商网站下载的驱动程序不起作用，则需要使用“设备管理器”手动选择设备和驱动程序。
Open the Start menu and type “Device Manager”. Select the first result. The Device Manager should appear, showing you each and every component and accessory on your PC in a nested list.
打开开始菜单，然后键入“设备管理器”。 选择第一个结果。 应出现设备管理器，以嵌套列表的形式显示PC上的每个组件和附件。
Your device might appear under its specific sub-section (keyboards under “Keyboards,” webcams under “Imaging Devices,” and so on), but it’s more likely to be labelled as “Unknown Device,” either on its own or under the “Universal Serial Bus controllers” section. Right-click the device, then select “Update driver.”
您的设备可能会显示在其特定的子部分(“键盘”下的键盘，“成像设备”下的网络摄像头等)下，但更有可能被单独标记为“未知设备”，或在“通用串行总线控制器”部分。 右键单击设备，然后选择“更新驱动程序”。
Click “Browse my computer for driver software.”
单击“浏览我的计算机以获取驱动程序软件。”
On the next screen, click “Let me pick from a list of available drivers on my computer.”
在下一个屏幕上，单击“让我从计算机上的可用驱动程序列表中选择”。
On this screen, you’ll be lucky if you can see the driver you’ve manually installed from the included disc or the web. If not, remove the checkmark from “Show compatible hardware” to see a list of all the drivers currently installed on your machine. Click on the appropriate manufacturer in the left pane, then the correct driver on the right.
在此屏幕上，如果您可以从随附的光盘或网络中看到手动安装的驱动程序，将会很幸运。 如果不是，请从“显示兼容的硬件”中取消选中标记，以查看计算机上当前安装的所有驱动程序的列表。 单击左侧窗格中的相应制造商，然后单击右侧的正确驱动程序。
Click “Next” to manually install the driver. Your device should hopefully be detected and working now, though you may need to reboot your PC for it to start up.
单击“下一步”以手动安装驱动程序。 尽管您可能需要重新启动PC才能启动设备，但还是希望它能够被检测到并可以正常工作。
您的USB控制器可能出现问题 (Your USB Controller Might Be Experiencing Problems)
A USB controller is the part of your computer’s motherboard (or sometimes the part of the PC case that connects to it) that includes the USB port and the electronics that connect it to the PC itself. These components also need driver software, though they’re almost always detected and installed automatically by Windows.
USB控制器是计算机主板的一部分(有时甚至是与其连接的PC盒的一部分)，其中包括USB端口和将其连接至PC本身的电子设备。 这些组件也需要驱动程序软件，尽管Windows几乎总是自动检测并安装它们。
It’s less likely, but possible, that your USB controller itself could have a driver error. Try to track down the controller driver from your manufacturer (Dell/HP/Lenovo, etc. for most machines, or the manufacturer of your motherboard like GIGABYTE/MSI/ASUS if you assembled your own PC) and install it. If it’s still not working, follow the steps in the section above to select it manually.
USB控制器本身可能会出现驱动程序错误，但这种可能性较小，但有可能。 尝试从制造商(大多数机器的Dell / HP / Lenovo等)或主板制造商(如GIGABYTE / MSI / ASUS，如果您组装了自己的PC)中查找控制器驱动程序并进行安装。 如果仍然无法使用，请按照上述部分中的步骤手动进行选择。
您的USB设备可能有物理缺陷 (Your USB Equipment Might Have a Physical Defect)
The last and most unfortunate possibility is that there’s a physical error or defect with your equipment. You can try the usual stuff for this—use a different USB cable if you can, switch to a different USB port, do away with any hubs or extensions you might be using—but if there’s something wrong with the USB controller or device itself, your options are limited. At that point you’ll need to either replace the controller (which typically means replacing the motherboard, and often the whole machine) or the gadget. Test out the gadget on other computers to rule out the latter possibility.
最后也是最不幸的可能性是设备存在物理错误或缺陷。 您可以尝试使用通常的方法-如果可以，请使用其他USB电缆，切换至其他USB端口，取消可能要使用的任何集线器或扩展件-但如果USB控制器或设备本身有问题，您的选择是有限的。 届时，您需要更换控制器(通常意味着更换主板，通常是整个机器)或小工具。 在其他计算机上测试小工具，以排除后一种可能性。
If you know what you’re doing, it’s possible to replace and re-solder a defective USB port, either on your computer itself or on the device. But even that’s really only an option for desktops; laptops require basically a complete disassembly to access the USB hardware on the motherboard, which tends to void the warranty anyway.
如果您知道自己在做什么，则可以在计算机本身或设备上更换并重新焊接有故障的USB端口。 但这实际上只是台式机的一种选择。 笔记本电脑基本上需要完全拆卸才能访问主板上的USB硬件，这总会导致保修失效。
