Any USB device connected to a Windows computer has a polling rate. This is the rate at which data is sent from the computer to the device. A higher rate can allow for greater response, and a lower rate can reduce power consumption. Getting the balance right is usually handled automatically by the Windows computer. However, there is a way of manually setting USB polling rates.
