Both PS/2 and USB allow the sample rate to be overridden, with PS/2 supporting a sampling rate of up to 200 Hz [5] and USB supporting a polling rate up to 1 kHz [3] as long as the USB mouse runs at full-speed or higher USB speeds.
All of the mice have a polling rate of 1000 Hz. The polling rate of a mouse is how many often it notifies the computer of its location each second, with each Hz equaling one register. [22] In November 2017, Razer introduced the Naga Trinity. This mouse has interchangeable side panels, meaning the user could choose how many buttons they wanted.
A poll message is a control-acknowledgment message.. In a multidrop line arrangement (a central computer and different terminals in which the terminals share a single communication line to and from the computer), the system uses a master/slave polling arrangement whereby the central computer sends message (called polling message) to a specific terminal on the outgoing line.
The maximum signaling rate in USB 2.0 is 480 Mbit/s (60 MB/s) per controller and is shared amongst all attached devices. Some personal computer chipset manufacturers overcome this bottleneck by providing multiple USB 2.0 controllers within the southbridge.
The xHCI reduces the need for periodic device polling by allowing a USB 3.0 or later device to notify the host controller when it has data available to read, and moves the management of polling USB 2.0 and 1.1 devices that use interrupt transactions from the CPU-driven USB driver to the USB host controller.
Contention in a wireless or noisy spectrum, where the physical medium is entirely out of the control of those who specify the protocol, requires measures that also use up throughput. Wireless devices, BPL , and modems may produce a higher line rate or gross bit rate , due to error-correcting codes and other physical layer overhead.
A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer.
USB OTG is a part of a supplement [2] to the Universal Serial Bus (USB) 2.0 specification originally agreed upon in late 2001 and later revised. [3] The latest version of the supplement also defines behavior for an Embedded Host which has targeted abilities and the same USB Standard-A port used by PCs.
