  • Device and method to emulate interrupts to provide PS/2 mouse and keyboard functionality for a USB mouse keyboard
    Patent number: 6496891
    Abstract: A device and method for generating interrupts to a central processing unit (CPU) for an universal serial bus (USB) keyboard and an USB mouse so that an operating system will treat these interrupts as if caused by an IBM™ personal computer series (PS/2) keyboard and PS/2 mouse. An interrupt request (IRQ) register having a first bit and a second bit is used to trigger the interrupts. A first merge unit acting as an OR circuit is connected to the first bit of the IRQ register to generate an interrupt to the CPU when the first bit is set to one. A second merge unit also acting as an OR circuit is connected to the second bit of the IRQ register to generate an interrupt to the CPU when the second bit is set to one.
