The contexts are designed so that they can be cached by the xHCI, and "paged" in and out as a function of endpoint activity. Thus a vendor can scale their internal xHCI Endpoint Context cache space and resources to match the practical usage models expected for their products, rather than the architectural limits that they support.
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.

USB 3.0 SuperSpeed – host controller (xHCI) hardware support, no software overhead for out-of-order commands; USB 2.0 High-speed – enables command queuing in USB 2.0 drives; Streams were added to the USB 3.0 SuperSpeed protocol for supporting UAS out-of-order completions USB 3.0 host controller (xHCI) provides hardware support for streams
If the data transfer is from the device to the host, the host sends an IN packet instead. If the destination endpoint is a uni-directional endpoint whose manufacturer's designated direction does not match the TOKEN packet (e.g. the manufacturer's designated direction is IN while the TOKEN packet is an OUT packet), the TOKEN packet is ignored.
One Extensible Host Controller Interface (xHCI) controller and two Enhanced Host Controller Interface (EHCI) controllers are integrated into the X99 chipset, providing a total of up to 14 USB ports. Out of those ports, up to six can be configured as USB 3.0 ports with speeds of up to 5 Gbit/s per port, while the remaining are USB 2.0 ports with ...
Support for rotating media – the bulk protocol is updated with a new feature called Stream Protocol that allows a large number of logical streams within an Endpoint USB 3.0 has transmission speeds of up to 5 Gbit/s or 5000 Mbit/s, about ten times faster than USB 2.0 (0.48 Gbit/s) even without considering that USB 3.0 is full duplex whereas ...
In telecommunications networks, a node (Latin: nodus, ‘knot’) is either a redistribution point or a communication endpoint.. A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1]
