PERIPHERAL DEVICE, SYSTEM INCLUDING THE PERIPHERAL DEVICE AND METHOD

The invention relates to a peripheral device for communicating with a host and for controlling a controlled device, to a system including such peripheral device and at least the controlled device andto a corresponding method including a communication and a controlling. In order to allow for a possibility for upgrading controlled devices with further functionality during their service life at lowinitial costs or efforts on the side of the controlled devices, it is provided for an interconnection between a portion of the system using a complex standard and another portion of the system not using such standard by means of the peripheral device having a dual purpose, as a peripheral device to the standard compliant host and as a controlling device to the controlled device. In both cases, however, power is provided to the peripheral device from either the host or from the controlled device. 本发明涉及种用于与主机通信和用于控制受控设备的外围设备，涉及种包括这样的外围设备和至少所述受控设备的系统，并且涉及种包括通信和控制的相对应的方法。为了允许在受控设备的使用寿命期间以所述受控设备侧的低的初始成本或努力将所述受控设备升级为具有另外的功能性
