Embodiment Construction

[0031] Next, the best mode for carrying out the present invention will be described using the drawings. figure 1 It is a configuration diagram showing a schematic configuration of the Wireless USB system 10 which is an embodiment of the present invention. The wireless USB system 10 of this embodiment includes: a printer 20, which is a dual-function device having functions as a USB host and a USB device, and performs printing of printing data; and a digital camera 40, which has functions as a USB host and a USB device. and a personal computer (PC) 60, as a USB host, exchanges information with the printer 20 and the digital camera 40 via a wireless (wireless) USB. In addition, although the digital camera 40 of this embodiment is shown as an example of a dual-function device, it may be configured to have only the USB device function.

[0032]The printer 20 includes: a known controller 21 for controlling the entire device; a printing mechanism 25 for printing on recording paper S...

Abstract

The invention provides a USB device, a printing apparatus, a control method of the USB device and program thereof, and makes wireless communication between a USB host side apparatus and a USB device machine smoother. The printing apparatus (20) has a USB device (30). The USB device (30) has a transmission / reception unit (32) that wirelessly performs transmission / reception of data to / from a USB host side apparatus; a transmission / reception unit (33) that is provided separately from the transmission / reception unit (32) and wirelessly performs transmission / reception of data to / from a USB device side apparatus. And during an execution period based on a period for which the USB device (30) receives printing data from an apparatus machine (digital camera (40)), information, which indicates that data processing is being performed, is transmitted to the USB host side apparatus (a user PC (60)). Therefore, when the USB device (30) cannot process data from the USB host side apparatus, the USB device previously transmit the information to the USB host side apparatus.

Description

technical field [0001] The invention relates to a USB device, a printing device, a control method of the USB device and a program thereof. Background technique [0002] In the past, as a USB device, it has been proposed to be disposed on an image output device, to exchange data between a USB device and an image output device in a wireless USB device, and to perform data exchange between an image output device and a USB host. A USB device that functions as a host cable adapter for switching (for example, refer to Patent Document 1). In the USB device described in this Patent Document 1, the USB host device and the USB device device can exchange information through a single wireless USB interface. [0003] However, the image output device provided in the USB device described in Patent Document 1 operates as both a USB device and a USB host. Here, when data is transmitted and received with either the USB device device or the USB host device, the image output device may perfor...
