What is the correct order for installation of a new USB device and driver files?

The correct sequence for installing a new USB device and its driver files is to first install the device driver, then attach the device, and finally complete the Add a Device wizard. This order is significant for several reasons.

When you install the device driver first, the operating system is prepared to recognize and communicate with the new device as soon as it is connected. The driver acts as a translator between the device and the operating system, allowing seamless interaction. Once the driver is installed, attaching the device allows the system to recognize it and establish the necessary communication via the already-installed driver.

Completing the Add a Device wizard as the final step allows for any additional configuration that may be necessary for the device's full functionality. Depending on the operating system and the USB device, the wizard may offer options for setup or troubleshooting.

This ordering helps ensure that there are minimal issues during the setup process, as the system is already equipped to handle the device once it is connected. In contrast, connecting the device before the driver is in place can lead to the device not being recognized properly, or it could lead to complications in installation due to the operating system not being ready to interface with the new hardware.
