The polling timeout specifies the amount of time the system waits for a response to a poll. The default is 700 milliseconds.

Whenever you increase the polling timeout, pay attention to the effect on the cumulative value for the polling timeout. On each successive retry, the polling timeout is doubled. The cumulative polling timeout should always be less than the polling interval, else the device could be polled excessively. Consider reducing the number of retries when increasing the polling timeout.
