USB dongle correlating a device class to the protocol of a wireless device
A USB device includes: a communication section that is capable of wirelessly communicating with a communication device that supports a predetermined communication standard; a USB communication section that is capable of communicating with a USB host device; and a connection section that, when a connection to the communication device is requested under the condition that a connection to the USB host device is requested, determines whether or not a protocol supported by the communication device is any of multiple protocols, and establishes the connection to the USB host device through the USB communication section using a device class corresponding to the determined protocol.
1. A USB device comprising:
a communication section that is capable of wirelessly communicating with a communication device that supports a predetermined communication standard;
a USB communication section that is capable of communicating with a USB host device; and
a connection section that, when a connection to the communication device is requested under the condition that a connection to the USB host device is requested, determines whether or not a protocol supported by the communication device is any of multiple protocols, and establishes the connection to the USB host device through the USB communication section using a device class corresponding to the determined protocol.
2. The USB device according to claim 1 ,
wherein when the connection to the USB host device is requested, the connection section stands by without establishing the connection to the USB host device, and when the connection to the communication device is requested, the connection section establishes the connection to the USB host device.
3. The USB device according to claim 2 ,
wherein the predetermined communication standard is TransferJet, and the communication device is a TransferJet device.
4. The USB device according to claim 1 that is capable of being connected, via a USB connection, to a printing device that serves as the USB host device.
5. A USB device comprising:
a communication section that is capable of wirelessly communicating with communication devices that support a predetermined communication standard;
a USB communication section that is capable of communicating with a USB host device; and
a connection section that, when a connection to one of the communication devices is requested under the condition that a connection to the USB host device is established and a connection to another one of the communication devices is established, disconnects the connection to the USB host device and the connection to the other one of the communication devices, determines whether or not a protocol supported by the one of the communication devices is any of multiple protocols, and reestablishes the connection to the USB host device through the USB communication section using a device class corresponding to the determined protocol.
6. The USB device according to claim 5 ,
wherein the connection section disables the connection to the USB host device when disconnection from the communication device is requested.
7. The USB device according to claim 6 ,
wherein the predetermined standard is TransferJet, and the communication devices are TransferJet devices.
8. The USB device according to claim 7 ,
wherein when the connection section determines that the protocol supported by the TransferJet device is Small Computer System Interface, the connection section establishes the connection to the USB host device using Mass Storage Class, and when the connection section determines that the protocol supported by the TransferJet device is OBject EXchange, the connection section establishes the connection to the USB host device using a Bluetooth class.
9. The USB device according to claim 5 that is capable of being connected, via a USB connection, to a printing device that serves as the USB host device.
