Mediating communciation of a univeral serial bus device

摘要

An apparatus for mediating communication between a universal serial bus (USB) device and a host computing device is described. In an example, the apparatus includes a USB host interface configured to be connected to a downstream USB device, and a USB device interface configured to be connected to an upstream host computing device. The apparatus also includes a mediation module positioned between the USB host interface and the USB device interface and configured to determine whether the USB device is authorized to communicate with the host computing device.

1. An apparatus to mediate communication between a host computing device and a universal serial bus (USB) device, the apparatus comprising:
a universal serial bus (USB) host interface configured to be connected to a downstream USB device; a USB device interface configured to be connected to an upstream host computing device; and a mediation module positioned between the USB host interface and the USB device interface and configured to determine whether the USB device is authorized to communicate with the host computing device, wherein, after the mediation module determines that the USB device is authorized to communicate with the host computing device, the mediation module is configured to transmit one or more messages between the USB host interface and the USB device interface and to monitor the one or more messages to detect device emulation by the USB device of a device other than the USB device.
