TL;DR: In this paper, a storage unit made of a flash array (58) and a Universal Serial Bus (USB) controller (56) is implemented to be compatible with the USB specification.
Abstract: A storage unit made of a flash array (58) and a Universal Serial Bus (USB) controller (56) is implemented to be compatible with the USB specification. The unit (46) includes memory modules (58) which can accept write commands and read commands from a host (44), and are erasable and non-volatile, referred to as flash modules (58). The USB/flash controller (56) is configured to provide USB functionality and compatibility along with common flash operations such as programming, reading, and erasing the flash modules (58).

TL;DR: In this paper, a management sub-system includes a Composite USB function logic device that connects to the USB controller in the server, and emulates the various peripherals available at the management console.
Abstract: A management sub-system connects via a USB bus to a server or computer being managed. The management sub-system also couples to a management console, which has a number of conventional peripherals, including CD-ROM, floppy drive, hard disk, keyboard, mouse, and the like. These peripherals are emulated as USB peripherals coupled to the server by the management sub-system. The management sub-system includes a Composite USB function logic device that connects to the USB controller in the server. The Composite USB function logic device emulates the various peripherals available at the management console, and provides configuration data to the USB controller consistent with the emulation. Consequently, the server sends and receives data from these peripherals at the management console, as if the peripherals were locally connected by the USB bus to the server. The management sub-system monitors the operation of the server and publishes a web page that can be viewed by a web browser at the management console. In addition to viewing this status information, the management console can operate as a virtual terminal, capable of downloading files and programs from any of the emulated peripherals to the server, and of receiving input signals from the emulated input devices.

TL;DR: In this paper, an apparatus capable of operating as either a master device or a slave device on a communication link such as a Universal Serial Bus (USB) is described, and a timer is used to determine the presence or absence of an active host controller.
Abstract: An apparatus capable of operating as either a master device or a slave device on a communication link such as a Universal Serial Bus (USB). The apparatus includes a first communication port which is utilized when the apparatus is operating as a slave device. A second communication port is utilized when the apparatus is operating as a master device. A device controller is coupled to both the first communication port and the second communication port. The device controller enables either the first communication port or the second communication port after detecting whether an active host controller is coupled to the first communication port. A timer may be used to determine the presence or absence of an active host controller.

TL;DR: In this paper, an interface device is provided which enables communications between devices having disparate protocols (e.g., USB and Ethernet), and can be fabricated on a single integrated circuit (IC) chip.
Abstract: An interface device is provided which enables communications between devices having disparate protocols (e.g., USB and Ethernet), and can be fabricated on a single integrated circuit (IC) chip. A system incorporating the interface device provides plug-and-play capability for both MAC and nonMAC environments. A “smart” cable incorporating the interface device has the ability to recognize what type of external device using what type of protocol is connected to the “other” end of the cable, thereby enabling a host to communicate with the external device. An electronic component (e.g., integrated circuit) incorporating the technique is suitably included in a system or subsystem having electrical functionality, such as general purpose computers, telecommunications devices, and the like.
