BlackBerry device drivers are software packets that allow a BlackBerry mobile phone to communicate with your computer. Device drivers are necessary if you plan on synchronising your BlackBerry to your computer or transferring files to it via a USB cable. You may also remove and re-add BlackBerry device drivers if you are experiencing a synchronisation issue. Uninstalling programs such as BlackBerry Desktop Software does not remove the device drivers from your computer. Those must be removed manually.
