Abstract
A controller and a control method for a controller can simplify application development and can improve the performance of device control processes. When a request is received from an applicationand the received process request is an initialization request, whether or not the received request is the first initialization request received after the applicationstarted running is determined. If the received initialization request is the first initialization request, the request is passed to the device driverand initialization settings information describing the configuration of the device driverafter the initialization process ends is stored. If an error has occurred in the device driverwhen the device driverstatus is detected, an error handling process is executed according to the device driverstate. When the device driverhas recovered, a request for setting the device driverstate to the state based on the initialization settings information is asserted.
