Simplified Device Drivers For Hardware Devices of a Computer System

One or more computer-readable media having a tangible component and computer-readable instructions therein that, when executed by a computer system, cause the computer system to perform acts comprising:

• interacting, by a first device driver not required to have knowledge of operation commands specific to a hardware device, with an application running on the computer system through a device driver interface to receive from the application a request for performing a requested operation by the hardware device;
• setting parameters associated with the requested operation;
• and
• calling, by the first device driver and with the parameters, entry point functions of a second device driver capable of translating a pre-selected set of operation commands generic to different device models and brands of the given device type into operation commands specific to the hardware device to control the hardware device to perform the requested operation, the entry point functions corresponding to the pre-selected set of operation commands generic to the different device models and brands of the given device type and callable by the first device driver for controlling operations of said hardware device.
