What if the card reader can't read it?
In the process of using the card reader, we occasionally encounter the problem that the card reader does not read. So, the reader can not read out how to do? In fact, the reader does not read out for several reasons, may be the reader itself, but also may be the computer side of the problem, we may use the elimination method to solve.
If you insert a card reader in another computer, the card reader is normal, then the original computer failed. Computer Setup Failure Solution:
1, then to the original computer click "Start-Control Panel-Add New hardware-find" and then find out if there is no external equipment, if any, you can open click "Hardware" will be driven to unload, and then insert the card reader, reinstall the driver.
2, of course, can enter into Safe mode, and then repair the registry, and then re-enter the normal mode to plug the card reader, to see the failure resolved.
3, if the failure is still the case, then try to restore the computer to the failure of the time, or the electrical system disk repair, open a command prompt input Sfc/scannow carriage return, and then insert the system disk repair. There is no need for us to fix it, and the system will automatically detect the fix.
4, if the failure is still, set the optical drive in the BIOS for the first boot device Insert system installation disk press R to select "Repair Installation" can be.
5, the lack of USB power supply causes. This may be caused by too much external devices on the USB interface.
Workaround: Right mouse button "My Computer (computer)-Device Manager-Find the Universal Serial Bus Controller" option, then, on the dropdown list of options, there are "USB Root Hub" options, double-click the option, and then open the Properties dialog box, switch to the Power Management tab, and remove the Allow the computer to turn off this device to save power "before the check, click OK."
If the card reader fails, check to see if the cable connection is broken. Then there is the failure of the interface. Try to change the interface. Of course, the small part of the proposed card reader is not very expensive, change a card reader bar.
