ABSTRACT:
When a device such as a printer is connected to a connector49via a USB cable using an electronic device40as a host, a selecting circuit43bis switched to a host function circuit43aby operating a switch42. When a host such as a personal computer is connected to the connector49via the USB cable using the electronic device40as device, the selecting circuit43bis switched to a device function circuit44aby operating the switch42. A USB interface is controlled according to output of a microcomputer41. Therefore, an interface circuit which meets USB standards, facilitates switching between a host function and a device function, has a simple circuit configuration and allows small-sizing can be provided.
