Abstract
For making a host computer automatically recognize a composite apparatus used with switching between functions thereof, the host 102 recognized whether a device is connected, based on a potential of cable data1. With switching between the functions of the apparatus, the device 100 temporarily stops supply of power to the cable data1 and restart the supply a predetermined time thereafter by R controller 205. When the supply of power is stopped, the host 102 assumes that the device is disconnected and deletes a driver for the device from a memory. When the supply of power is restarted thereafter, the host 102 recognizes the device 100 as a device having a new function, reads device information, and installs a driver suitable for the new device.
Claims40
A network system comprising a host device, and a composite apparatus capable of change in function, said composite apparatus being connected to said host device,
- wherein said composite apparatus comprises recognizing means for recognizing the change in function, and control means for performing such control as to make the host device recognize a function of the composite apparatus when said recognizing means recognizes the change in function.
A composite apparatus capable of change in function, said composite apparatus being connected to a host device,
- said composite apparatus comprising:
- recognizing means for recognizing the change in function;
- and
- control means for performing such control as to make the host device recognize a function of the composite apparatus when said recognizing means recognizes the change in function.
A control method of a composite apparatus capable of change in function, said composite apparatus being connected to a host device,
- said control method comprising:
- a recognition step of recognizing the change in function;
- and
- a control step of performing such control as to make the host device recognize a function of the composite apparatus when the change in function is recognized by said recognition step.
A storage medium for storing a control program of a composite apparatus capable of change in function, said composite apparatus being connected to a host device,
- said storage medium storing a program comprising:
- a recognition step of recognizing the change in function;
- and
- a control step of performing such control as to make the host device recognize a function of the composite apparatus when the change in function is recognized by said recognition step.
