Abstract
System and method in a USB environment for providing secondary management channel access to a managed system via a communications device connected to the managed system. The communications device can be shared between management channel use and system use. A remote management system can connect directly to the platform management subsystem of the managed system and the channel provides a communications path to the platform management subsystem under conditions where the host processor(s) and system software are unavailable. A management controller simulates the presence of the communication device to the USB host when the management controller takes ownership of the communication device. For non-USB communication devices, the management controller also converts data from non-USB format to USB format and routes the converted data to the USB host.
