What is Polling-rate?
The USB polling rate is the rate at which the USB controller checks the status of devices connected to it.
This is typically measured in Hertz (Hz), with higher polling rates indicating that the controller checks for device status more frequently.
The polling rate can affect the performance of devices connected to the USB controller, with higher polling rates potentially providing better performance.
However, in most cases the default polling rate set by the operating system is sufficient for most purposes.
Why is it important?
The USB polling rate is important because it can affect the performance of devices connected to the USB controller.
A higher polling rate can potentially provide better performance, as the controller is able to check for changes in device status more frequently.
This can be especially important for devices that require high-speed data transfer, such as external hard drives or gaming peripherals.
