Hi, When the BlackBerry device is connected by Universal Serial Bus (USB) cable to the computer, it is not detected as a BlackBerry Device on the Windows Device Manager. Universal Serial Bus controllers does not show any BlackBerry device, even though it has already been connected to the computer. It is because Blackberry Desktop Manager drivers are not registering with the Windows operating system. To resolve this issue, 1) Uninstall and reinstall the BlackBerry Desktop Manager. 2) Connect the BlackBerry device to another desktop computer to determine if the issue could be related to USB port hardware. 3) Update the BlackBerry device drivers manually. I hope this information will help you.
