Abstract

In some embodiments a method is disclosed that includes creating a network connection status between a host device and a peripheral network device, determining characteristics of the peripheral device such as receive capacity or a quality of service classification for the transmission and flow control for performing control and data transfers. A transfer is initiated when a uniform serial bus request block (URB) is generated by a host application. The URB can have parameters that can be utilized to generate a transaction over a wireless network providing Quality of Service (QoS) guarantees. Other embodiments are also disclosed.

Claims
