Abstract
An information processing apparatus which is capable of performing device connection control for connection to more devices than the maximum connectable devices defined by the device interface standard or the SDK. A device server communication module generates communication threads for controlling data communication with device servers according to requests from higher-layer software. Each communication thread generates a device stack for controlling a device via an associated device server connected thereto in such a manner as if the device were directly connected to the apparatus. When a connection notification indicative of connection with the device is received, the communication thread attempts to detect a device stack in a non-data transmission and reception state from the device stacks, and connects to the device server via the detected device stack to perform data transmission and reception.
