The connection and communication are performed, and the controlled device is controlled by the personal computer.
[0007]
USB brings the plug and play capabilities of computer peripherals out of the PC box. This specification eliminates the need to insert a card into a dedicated computer slot and reconfigure the system each time a peripheral device is attached to or detached from a PC. A USB-equipped personal computer can automatically configure a computer peripheral without having to reboot or run setup as soon as the computer peripheral is physically connected.
[0008]
USB also allows up to 127 devices to run simultaneously on a single computer, while peripherals such as monitors and keyboards function as additional plug-ins or hubs.
[0009]
By making such a USB connection, the personal computer can edit image data from, for example, a digital still camera, print out various processed data, or record desired data on an external information recording / reproducing device. Reproduction can be performed.
