Title: Methods and apparatuses for serial bus sideband communications

Abstract: Methods and apparatuses that utilize a serial bus, such as a universal serial bus (USB), for communications between a communications network, a computing device, and an auxiliary device are disclosed. Some embodiments comprise methods handling sideband communications using serial buses. One or more of the embodiments comprise differentiating in-band data from out-of-band data, transferring information of the in-band data between a communications network and a computing device, and transferring information of the out-of-band data between the communications network and an auxiliary device. Some embodiments comprise an apparatus having a communications network interface, an auxiliary device interface, and a computing device interface. Of the interfaces, one or more may be a serial bus interface. The apparatus may differentiate between in-band and out-of-band data and communicate information of the out-of-band data to an auxiliary device. In some embodiments, the apparatus may also transfer control information. In some embodiments, information may be routed based upon cyclic redundancy check (CRC) information.
