The PS/2 keyboard port is electrically and logically identical to the IBM AT keyboard port, differing only in the type of electrical connector used. The PS/2 platform introduced a second port with the same design as the keyboard port for use to connect a mouse; thus the PS/2-style keyboard and mouse interfaces are electrically similar and ...
Additionally, USB ports are color-coded according to the specification and data transfer speed, e.g. USB 1.x and 2.x ports are usually white or black, and USB 3.0 ones are blue. SuperSpeed+ connectors are teal in color. [2] FireWire ports used with video equipment (among other devices) can be either 4-pin or 6-pin. The two extra conductors in ...
A USB mouse or keyboard can usually be used with older computers that have PS/2 ports with the aid of a small USB-to-PS/2 adapter. For mice and keyboards with dual-protocol support, a passive adapter that contains no logic circuitry may be used: the USB hardware in the keyboard or mouse is designed to detect whether it is connected to a USB or ...
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
Free Spinning (toggled by software - various methods available) IR Laser: 800: 2.4 GHz: LY11, L-LL11: A Bluetooth (rather than RF) version of this mouse was bundled with the MX5500 keyboard starting in 2008. Replaced by Performance Mouse MX in 2009. VX Revolution 2006: 10: Free Spinning (toggled by mechanical switch) IR Laser: 800: QUAD 2.4 GHz ...
The commands needed to control a 16550 UART are much different from the commands needed to control an FTDI serial port converter, but each hardware-specific device driver abstracts these details into the same (or similar) software interface.
Chatpad and controller. The Microsoft Chatpad keyboard attachment (Model 1676), similar to the Xbox 360 Messenger Kit, was unveiled at Gamescom on August 4, 2015. [3] The Chatpad also includes the functions of the Stereo Headset Adapter and was bundled with the updated version of the Chat Headset terminating in a 3.5 mm headphone jack.
Color-coded PS/2 connection ports (purple for keyboards and green for mice) on the rear of a personal computer An S-video connector: because this is a female connector, Pin 1 is at lower right. Mini-DIN connectors are 9.5 millimetres (3 ⁄ 8 in) in diameter and come in seven patterns, with the number of pins from three to nine. Each pattern is ...
