Wireless USB device and wireless USB communication system

A wireless universal-serial-bus communication system comprising:

• a plurality of wireless universal-serial-bus hosts;
• and
• a wireless universal-serial-bus device that performs a communication conforming to a wireless universal-serial-bus standard with the wireless universal-serial-bus hosts, wherein
• the wireless universal-serial-bus device includes
• a reception-time-information receiving unit that receives reception time information indicating a data reception time specified by each of the wireless universal-serial-bus hosts,
• a configuration determining unit that determines, when the reception-time-information receiving unit receives the reception time information from a wireless universal-serial-bus host, whether a configuration is set for the wireless universal-serial-bus host that transmitted the reception time information,
• a configuration unit that sets, when the configuration determining unit determines that the configuration is not set for the wireless universal-serial-bus host that transmitted the reception time information, the configuration for the wireless universal-serial-bus host that transmitted the reception time information,
• a data receiving unit that receives data from each of the wireless universal-serial-bus hosts, and
• a host standby unit that causes, when the reception-time-information receiving unit receives the reception time information from a first wireless universal-serial-bus host while the data receiving unit receives data from a second wireless universal-serial-bus host, the first wireless universal-serial-bus host to standby until the data receiving unit completes receiving the data from the second wireless universal-serial-bus host, wherein
• the first wireless universal-serial-bus host holds data to be transmitted to the wireless universal-serial-bus device while the host standby unit causes the first wireless universal-serial-bus host to standby.
