Data Cable issues:
1. The Apple 6 Plus iOS8 system has a detection data line function. This may be the case, some friends have a number of Apple phones, may be mixed data line, resulting in computer can not recognize the Apple 5s phone. It is also possible to use a cottage version of the data line, if it is a shanzhai version of the data line, it is generally possible to charge only, can not be used for data transmission.
2. If this is the case, it is recommended not to use the cottage version of the data line, or to check whether the data line is confused.
Computer USB port or USB driver has problems:
1. If the data cable is not a problem, but also the original, then please check the computer's USB port is a problem. We can first try to replace a USB port on the computer, if still not, we can change a U disk plug up to see if the computer can identify.
2. If the USB disk is plugged in, the computer can identify, that means there is no problem with the USB port. If you are not able to identify the USB drive, please check the system for the problem of the driver.
