What is Legacy Device?
A legacy device refers to a computing device or device that is obsolete, obsolete, or no longer in production. This includes any device that is not supported or is no longer used frequently by most devices and software applications.
Typically, a legacy device consists of non-plug-and-play (PnP) devices that do not have a peripheral controller interface (PCI) and require manual configuration and jumper installation. A legacy device also includes computing devices that modern technology has made obsolete.
For example, because CD drives replace floppy drives, few new computers ship with built-in floppy drives. Similarly, legacy native devices are not supported by most modern software applications.
