About USB Driver:

In order for your phone to communicate with your PC, you need to install the proper USB drivers and connect the two via a USB cable. Your operating system may automatically install a generic USB driver, but these are often limited and do not offer the full range of features that drivers custom-tailored for your mobile phone usually offer.

It is highly recommended that you uninstall any previous Phone to PC USB drivers you may already have on your personal computer, because they may interfere with the installation process.

Most mobile phones come with an installation CD with software applications, including the USB driver that you need. You might not be interested in installing the Software Suite but, unfortunately, there is no workaround for some devices, and the only way to install the USB drivers is by installing the provided software.

When the software is outdated, it can cause problems when trying to get your device recognized by the computer. In this case, you should try to download the driver separately, making sure you choose the one that is specifically made for your device.

Make sure you regularly check with our website for new drivers so that you won't miss any updates. 

It is highly recommended to always use the most recent driver version available
