In order for any external device to be recognized by a computer via USB ports, the device should be either PnP (plug and play) or the device has a driver.
Check from the device manufacturer's website if it is PnP or not. Or, connect it to the computer, if it appears in Device Manager with a yellow symbol, it means it is not PnP and it needs a driver.
If the device has CD or DVD check if there is any driver available to be installed on the computer. or check the device manufacturer's website if they provide a driver for the device.
Please let me know if you need further assistance and keep me updated.
