\u0026nbsp;\u0026nbsp;\u0026nbsp; A card reader is a device that reads data from a memory card, but it can not only support data reads but also support data writing. Card readers are usually connected using USB and can access a variety of memory cards. The Usb card reader has a chip added to it, and can autonomously read and write the number. The card reader is used to insert a memory card. The memory card is generally used on smart phones, cameras and other electronic devices and is used to store data. However, it does not have an interface, and it must be connected to a computer through a card reader. Nowadays, usb card readers use multiple slot slots to meet different digital products to read data and are easy to use. \u0026nbsp;\u0026nbsp;\u0026nbsp; Through understanding the function of the card reader, to know that the card reader can be used normally, we must first be able to identify. So, what if we have a situation where the reader does not recognize it? \u0026nbsp;\u0026nbsp;\u0026nbsp; The reader does not recognize two things: 1. The card reader cannot be recognized by the computer; 2. The card reader cannot identify the storage device. \u0026nbsp;\u0026nbsp;\u0026nbsp; First, the reader cannot be recognized by the computer \u0026nbsp;\u0026nbsp;\u0026nbsp; Method One: \u0026nbsp;\u0026nbsp;\u0026nbsp; If the computer does not recognize the card reader, there may be a poor connection to the computer's main board interface, or it may be due to a bad card reader interface, or it may be that the memory card in the card reader is damaged. \u0026nbsp;\u0026nbsp;\u0026nbsp; Method Two: If you do not recognize a USB port plugged into your computer, unplug it and plug it into another jack. If not, replace it again until all USB ports are plugged in. \u0026nbsp;\u0026nbsp;\u0026nbsp; Method 3: \u0026nbsp;\u0026nbsp;\u0026nbsp; If all of your computer's usb slots are tried or not recognized, check the card reader's interface for deformation or foreign objects. If the card reader is normal, it is a motherboard interface problem that requires professional overhaul. \u0026nbsp;\u0026nbsp;\u0026nbsp; Method Four: The Reader in WIN8 System Cannot Be Recognized \u0026nbsp;\u0026nbsp;\u0026nbsp; Unrecognizable usb backup drive for;, devices in the lower right corner of the taskbar when a USB card reader is plugged in \u0026nbsp;\u0026nbsp;\u0026nbsp; There is a situation where the USB device cannot be recognized, and there are usually software and hardware related failures. Such as the USB interface is damaged (no prompt); or system-related services are prohibited (especially the abuse of optimization software); many friends mentioned BIOS, this situation is very rare (many people will move the BIOS). \u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp; In order to solve this problem, we first use other USB devices to detect if the USB interface is damaged, update the driver, enter the device manager, right click on the Unknown Device device, select Uninstall , and then restart the computer, then plug in the wireless device, let the system automatically identify the device is not installed driver \u0026nbsp;\u0026nbsp;\u0026nbsp;\u0026nbsp; Check whether the Plug and Play service is disabled. Press the Win+R key combination. In the run command input box, enter \u0026ldquo;services.msc\u0026rdquo; \u0026nbsp;\u0026nbsp;\u0026nbsp; In the service interface, in the right window in the middle of the window and double-click 'Plug and Play' service (to make the system automatically identify and adapt to hardware changes), double-click the service, in the service properties interface, click Start Type the down arrow behind the type, select manual or automatic, turn on the service. \u0026nbsp;\u0026nbsp;\u0026nbsp; At the time of the check, the situation may also be turned on. At this time, it can be disabled and then turned back on. You can ignore prompts to terminate or disable this service that can cause system instability. \u0026nbsp;\u0026nbsp;\u0026nbsp; Method 5: Reader light is on and the computer does not recognize \u0026nbsp;\u0026nbsp;\u0026nbsp; 1. Some readers require drivers, especially 64-bit WIN7 \u0026nbsp;\u0026nbsp;\u0026nbsp; 2. Causes of insufficient usb power supply. This situation may be caused by too many external devices on the USB interface. Solution: Right-click [My Computer - Device Manager - Find 'Universal Serial Bus Controller' option, then there are some 'usb Root Hub' options on the drop-down list of options \u0026nbsp;\u0026nbsp;\u0026nbsp; Double-click this option, and then open the Properties dialog box, switch to the 'Power Management' tab, remove the 'allow computer to turn off this device to save power' check before, click OK.
