Bulk transfer is one of the four USB transfers. These are nonperiodic, large bursty communications typically used for a transfer that can use any available bandwidth but can also be delayed until bandwidth is available.
A hardware mechanism for communication between the processor and a device, or between different devices. This term can also apply to processor-to-processor communication, such as with RapidIO or the processor local bus (PLB) on SMP and AMP systems.
The hardware device that controls signals on a bus. The bus controller hardware must be associated with a bus controller device driver in order for VxBus to make use of the device. The service that a bus controller device driver provides is to support the devices downstream from the controller. The bus controller driver is also responsible for enumerating devices present on the bus. See also device, driver, enumeration, and instance.
A VxBus procedure to create an instance whenever a new device or driver is made available. This procedure is used to determine if a given driver and device should be paired to form an instance.
A bus reset is a first signal sent by the host to the device once the host has detected a connect to the device on the bus. The control pipes should be created on a bus reset. See also control pipe.
A kind of bus, such as PCI or RapidIO. See also bus controller.
A CA cert is a digital certificates issued by a Certificate Authority.
A callback function is a routine defined by an application that is called back by library code in response to a message.
