Verify that BlackBerry device USB drivers are installed on your computer. When you install BlackBerry® Desktop Software from the CD
that came with your device, the correct USB drivers should be installed. You can also download the latest version of BlackBerry Desktop
Software from www.blackberry.com.
Verify that your computer is not in standby, hibernate, or sleep mode.
Some USB hubs might not provide enough power. Plug the hub into a power outlet (if available) and reconnect your device.
