ABSTRACT:
A method, apparatus, and article of manufacture for generating signals using a Universal Serial Bus (USB) host controller and USB keyboard. Data generated by the keyboard is marked as being used with an operating system which responds to keyboard generated interrupts and which reads keyboard data stored in a register. The marked data is detected after it is received from the keyboard and is transferred to a register. An interrupt to a central processing unit (CPU) is then generated in response to the marked data being transferred to the register.
