Abstract: Provided are Universal Serial Bus (USB) wireless network card configuration methods, a host, a USB wireless network card and a communication system. A host enters a configuration mode after connecting with a USB wireless network card, acquires, in the configuration mode, configured interface combination information including each function interface configured by a user, and then sends the configured interface combination information to the USB wireless network card.

Abstract: A communication device based on a USB interface and a method for implementing service configuration are provided. The method is used for the communication device based on the USB interface, comprising: said communication device based on the USB interface reporting a device descriptor to a host, thus making said host complete loading of a host driver; said communication device based on the USB interface receiving a control instruction sent from the host side through the USB interface; and said communication device based on the USB interface configuring service attribute information according to said control instruction, so as to enable said service attribute information to indicate service attributes of said communication device based on the USB interface. The USB control information controls the service attribute information such that said device can implement support to service differentiation aiming at different operating systems.
