Abstract
A data transfer system, which comprises a system host and an adaptor including a local host, is provided. The adaptor is connectable to a local device inserted into the adaptor and includes a switch unit configured to perform address translation and Requestor (Req) ID translation for data transfers between the local device and the system host. The system host checks, when the local device is inserted or removed while the system host is in operation, a type of a protocol applied to the local device and reloads a device driver based on a result of the check. The device driver includes a pre-sleep state storage configured to store an insertion and removal state of the local device immediately before the system host and the adaptor enter a sleep state.
