1、现在扫描仪市场中的绝大多数产品都是 USB 接口的，这种接口类型的扫描仪虽然安装使用起来比较方便，但遇到一些特殊工作环境，USB 扫描仪还有可能无法被系统成功识别到。下面，本文就来分析一下有关 USB 扫描仪无法被计算机系统准确识别到的几种因素，并为各种因素提供相应的解决办法，以帮助各位能有效地用好 USB 扫描仪。Now the vast majority of products scanner in the market is USB interface, this interface type scanner while the installation more convenient
2、to use, but in some special working http:/ environment, USB scanner and may not be successful to system identification. Here, we have to analyze several factors related to USB scanners cannot be accurately identified by the computer system, and provides the corresponding solutions for a variety of f
3、actors, to help you can effectively use the USB scanner.因素 1、前置 USB 端口线序不对Factor 1, front USB port line sequence.通常大家在挑选机箱时，机箱说明书会提示我们，前置 USB 端口在计算机主板上是怎样走线的，我们只有按照提示正确连接好线序，才能保证前置 USB 端口正常发挥作用。要是我们在装机过程中，不按照提示正确连接好 USB 端口与主板之间的连线时，USB端口不但不能正常工作，而且有可能会将插入的扫描仪接口烧毁。因此如果扫描仪插入到机箱的前置 USB 端口中，发生系统无法成功识别 U
4、SB 扫描仪的现象时，那多半是前置 USB 端口线序不对造成的，此时唯一的办法就是将扫描仪重新插入到集成在主板中的后置 USB 端口！Usually people in the selection of the chassis, chassis specification will prompt us, front USB port on the http:/ computers motherboard is how to walk the line, we can only follow the prompts correct connection line order, to ensure
5、 the front USB ports play a role in normal. If we in the installation process, do not follow the correct connection between the USB port and the motherboard connection, USB port can not work normally, but may be inserted into the burning scanner interface. So if the scanner is inserted into the http
6、:/ chassis front USB ports, generating system cannot successfully identified USB scanner phenomenon, it is mostly front USB port line sequence does not cause, the only way is to set the scanner re inserted into the post USB integrated on the motherboard port!小提示：机箱前面的 USB 端口通常没有与机箱外壳进行接地，所以当人用手将扫描仪的
7、 USB 接口插入到计算机的前置 USB 端口中时，人体身上的静电将无法通过地线释放出来，如此一来强大的静电电流就会对计算机主板产生不小的冲击，严重的话能损坏主板的相应接口。为此，我们在插入 USB 扫描仪时，尽量不要用手直接接触到扫描仪USB 接口的金属部分。Tip: the front of the chassis USB ports usually no grounding and chassis shell, so when people use their hands to the USB interface scanner into the computer in front of
8、 the USB port, electrostatic human body will not be released through the ground, so that the electrostatic strong flow will have no small computer motherboard the impact of the corresponding interface, serious word can damage the motherboard. Therefore, we insert the USB in the scanner, try not to h
9、and in direct contact with the scanner USB interface of the metal parts.因素 2、系统或 CMOS 设置不对2 factors, system or CMOS settings wrong这种因素由于很少碰到也许会容易被大家忽略掉。有的时候，我们的 USB 扫描仪无法被计算机成功识别到，仅仅是由于自己在计算机的设备管理器中或 BIOS 参数中禁用了主板上的 USB 端口。在检查主板的 USB 端口是否已被禁止时，只需要重新启动一下计算机系统，进入到系统的 BIOS 设置界面，找到该界面中的“Chipset Features
10、 Setup”项目或“Integrated Peripherals”项目，然后看看对应项目中的“Onchip USB”数值是“Disable”还是“Enable”，要是为“Disable”的话就表明计算机已经禁用了 USB 端口，扫描仪插入到对应端口时系统当然无法识别到它的存在；为此我们必须将“Onchip USB”数值重新设置为“Enabled”，再执行一下保存操作，并将计算机系统重新启动一下，才能激活主板上的 USB 端口，只有这样 USB 扫描仪才有可能被系统识别到。Such factors as rarely encountered may be overlooked. Sometim
11、es, we USB scanners cannot be successfully identified by computer, just because of their own in the device manager in a computer or BIOS parameter is disabled in the USB ports on the main board. In the check whether the motherboard USB ports have been banned, only need to restart the computer system
12、, access to the system BIOS interface, the interface is found in the “Chipset Features Setup“ or “Integrated Peripherals“ project project, and then have a look the projects in the “Onchip USB“ is “Disable“ or “Enable“ if, as the word “Disable“ indicates that the computer has disabled the USB port, i
13、nserted into the corresponding port scanner system cannot recognize the existence of it; therefore we must have “Onchip USB“ numerical re set to “Enabled“, and then perform a store operation, and then restart the computer system, to activation of the USB ports on the main board, the only way USB sca
14、nner can be recognized by the system to.因素 3、系统服务被意外停止3 factors, system service is stopped unexpectedly一般情况下，初次将 USB 接口的扫描仪插入到主板上的 USB 端口中时，计算机往往会自动识别到扫描仪，并会打开一个驱动程序安装提示界面，我们只要根据提示正确地安装好扫描仪驱动程序就能开始正常扫描操作了。如果初次安装扫描仪时，计算机系统并不自动打开驱动程序安装提示界面的话，在排除了上面的因素后，很有可能是Windows 系统的 Plug and Play 服务被意外禁用了，这样就会阻碍系统自
15、动识别到 USB扫描仪。为了避免因系统服务被意外停止而导致无法识别扫描仪的故障，我们可以按如下办法检查一下 Plug and Play 的服务运行状态：Under normal circumstances, will be the first time USB interface scanner that plugs into the motherboards USB port, the computer will automatically recognize the scanner, and will open a driver installation prompt interface,
16、 we as long as according to the prompt correctly installed scanner driver can begin normal scan operation. If the initial installation of the scanner, computer system does not automatically open the driver installation prompt interface, after exclusion of the above factors, is likely to be the Windows Plug and Play service system is accidentally disabled, it will hinder the automatic identification system
