Such passive adapters may be specific to the devices they came with; however, the most common configuration involves sharing the GND and Vcc (+5 V) pins of both protocols, connecting the USB D+ pin to the PS/2 +CLK pin, and connecting the USB D- pin to the PS/2 +DATA pin. Using such adapters requires a dual-mode controller on the keyboard or ...
Simple adapters exist both for plugging PS/2-hardware into USB sockets, as well as for plugging USB-hardware into PS/2 sockets. -- Alexey Topol 16:31, 27 March 2010 (UTC) Yes, a section about adapters is appropriate. I bought an inexpensive adapter to connect a Logitech M-S48 PS/2 mouse and a Microsoft PS/2 Intellimouse to USB sockets.
Circuit designers will sometimes refer to this class of components as dissipative, or thermodynamically passive. While many books give definitions for passivity, many of these contain subtle errors in how initial conditions are treated and, occasionally, the definitions do not generalize to all types of nonlinear time-varying systems with memory.
The keyboard controller also handles PS/2 mouse input if a PS/2 mouse port is present. Today the keyboard controller is either a unit inside a Super I/O device or is missing, having its keyboard and mouse functions handled by a USB controller and its role in controlling the A20 line becoming integrated into the chipset's northbridge and then ...
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 ...
For electronics hobbyists the parallel port is still often the easiest way to connect to an external circuit board. It is faster than the other common legacy port (serial port), requires no serial-to-parallel converter, and requires far less interface logic and software than a USB target interface.
For instance, the 1997 Microsoft Precision Pro joystick was re-introduced in a version that used a game port connector, but also included a USB adapter in the box. [19] The rapid takeover of USB meant that this was superfluous when the Precision Pro 2 was released the next year in 1998.
The official multitap for the PlayStation The official multitap for the PlayStation 2. The PlayStation Multitap is a peripheral for the PlayStation.It is an adapter that can be used to plug in up to four controllers and memory cards at the same time in a single controller port.
