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.
Both PS/2 and USB allow the sample rate to be overridden, with PS/2 supporting a sampling rate of up to 200 Hz [2] and USB supporting a polling rate up to 1 kHz [11] as long as the mouse runs at full-speed USB speeds or higher, while USB 2.0 capable devices can support up to 8 kHz polling rates.
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.

Bluetooth 5 has introduced two new modes with lower data rate. The symbol rate of the new "Coded PHY" is the same as the Base Rate 1M PHY but in mode S=2 there are two symbols transmitted per data bit. In mode S=2 only a simple Pattern Mapping P=1 is used which simply produces the same stuffing bit for each input data bit.
