The xHCI is a radical break from the previous generations of USB host controller interface architectures (i.e. the Open Host Controller Interface (OHCI), the Universal Host Controller Interface (UHCI), and the Enhanced Host Controller Interface (EHCI)) on many counts.
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.
As an example, assume the case of Wake-on-LAN. Traditionally, the OS controls Wake-on-LAN and must call third-party device drivers to enable support on a network card. With the HECI bus, the host is able to assert its request line (REQ#), the ME will assert its grant line (GNT#), and the host can send its message using its serial transmit signal.
An INF file (setup Information file) is an INI plain-text file used by Microsoft Windows-based operating systems for the installation of software and drivers. [1] INF files are most commonly used for installing device drivers for hardware components. [ 2 ]
Host Controller Interface or Host controller interface may refer to: . Host Controller Interface (FireWire), an interface that enables a FireWire host controller to communicate with a driver
HAL is a single daemon responsible for discovering, enumerating and mediating access to most of the hardware on the host computer. Applications communicate with HAL through the D-Bus IPC mechanism, which abstracts the hardware behind an object-based RPC mechanism.
The autorun.inf file can also specify an icon which will represent the device visually in Explorer along with other advanced features. [ 1 ] The terms AutoRun and AutoPlay tend to be interchangeably used when referring to the initiating action, the action that detects and starts reading from discovered volumes .
Assuming Registry settings allow AutoRun, then the following autorun.inf handling takes place: Windows versions prior to Windows XP; On any drive type, the autorun.inf is read, parsed and instructions followed immediately and silently. [8] The "AutoRun task" is the application specified by the open or shellexecute keys. If an AutoRun task is ...
