Abstract
A firmware of the image forming device stores USB configuration information in a memory when updating the firmware in a normal operation. When updating of the firmware is not completed normally, the image forming device operates a recovery operation by executing a recovery program. The recovery program transmits USB configuration information, which is stored in the memory, to a terminal device when performing USB communication with the terminal device in the recovery operation. Thus, the USB configuration of the normal operation and that of the recovery operation are identical.
