Adapters Bring Together the Old and the New, & That’s Good! When it comes to connecting accessories to computers, it is not always with a USB to USB cable. Even after the invention of the USB standard, the various types of serial connectors stayed. Everything did not immediately switch to USB entirely. This is when manufacturers started to find a middle ground because they did not want their accessory to be useless (or, out of time) in a short time. So, they started making devices that could connect to a computer via its USB port while the device itself retains its serial port. They shipped their device with a USB to serial adapter.
