Nowadays, electronic products are used more and more in our lives. For photos and music, you can't just hope that it exists in mobile phones, cameras, and even more in the computer. So a gadget to pass data is there, and that's the card reader. But sometimes the card reader still has some problems, that is, it will encounter the case that the card reader does not respond to the computer. What are we going to look at?
    Generally speaking, if the card reader has a good quality, the reader will not be able to respond when the card is inserted. Can't be used on one computer, you can try to look at another computer, if another computer can, then this is the problem with the computer settings. If the problem appears on the computer, how can you solve it?
If the reader does not respond to the computer, the first consideration is the problem of the reader driver, so we can reinstall the driver of the reader. Open the control panel on your computer, find "Add New Hardware" in the panel, find "Find", find it in the list, find the driver related to the external device, then uninstall it, then insert the card reader and reinstall the related driver.
    You can also consider fixing the registry to fix the problem. You can enter safe mode, then repair the registry, and then re-enter the normal mode to insert and remove the card reader to see if the fault is resolved. If the fault persists, set the CD-ROM drive in the BIOS to insert the system boot disk into the first boot device and press R to select “Repair Installâ€.
    Or it is because of hardware problems, which is caused by insufficient power supply of usb. This situation may be caused by too many external devices on the usb interface. Find the device manager, then find the "Universal Serial Bus Controller" option. There are some "usb Root Hub" options on the drop-down list of this option. Double click on it. Options, then open the properties dialog, switch to the "Power Management Tab", remove the check box before "Allow the computer to turn off this device to save power", click OK.
    The above operation can be said to completely check the problem that cannot be read due to the computer. If after the above operation, the problem that the card reader is not responding to the computer is still not solved, then it is considered whether it is caused by the problem of the card reader itself.
