If the device is configured, it will always respond with a report for this command, even if no motion

or button changes have occurred. In this case, it would report 00 for motion and simply report the

current button state. If a report is pending on endpt1, the data there will be reported and the report

on endpt1 cleared.

The mouse will only create new button/motion packets when it is in the Configured state
