Abstract
A memory in a controller device stores a current function information list, which is a list of function information of each target device currently connected to an IEEE 1394 serial bus network, and also stores a past function information list which is a list of function information of each target device having been connected to the network in the past. When the controller device gets a GUID from a target device after bus reset, the controller device searches for a record of the target device corresponding to the gotten GUID from the records in the current function information list and the past function information list prior to the bus reset. As a consequence, if the controller device finds a record of the target device corresponding to the gotten GUID, the controller device copies such record in the current function information list or the past function information list prior to the bus reset, and stores the copied record in a current function information list made after the bus reset.
