Final answer:
Of the items listed, a lightweight table cannot be connected using a USB port, as it is not a peripheral device and lacks electronic functionality.
Step-by-step explanation:
The question asks which item from a given list cannot be connected using a USB port. USB ports are commonly used to connect peripheral devices such as a CD player or portable electronic devices to a computer. These devices typically include things like flash drives, printers, external hard drives, and speakers that can play music from a CD or mp3.
However, a lightweight table cannot be connected using a USB port, as it is not a peripheral device and does not have any electronic or data transfer function.
