Abstract
A system and method for detecting and gracefully recovering from a peripheral device fault has been disclosed. The method detects whether a peripheral device has suffered from a peripheral device fault. Where the peripheral device fault has occurred, the method determines whether any of a plurality of processes executable by the peripheral device is currently being executed by the peripheral device. The plurality of processes comprises those process which could result in significant loss of data, loss of connection to a network or adversely affect the performance of the peripheral device if the peripheral device is reset during execution of any of the plurality of processes. If none of the plurality of processes is being executed by the peripheral device, the method automatically resets the peripheral device. According to the method and system disclosed, peripheral devices can be made to recover from faults without user intervention, without loss of connection to any networks, and with minimal loss of data. Reliability is improved, thereby increasing overall system performance.
