The time delay between i2c_hid_set_power and i2c_hid_set_or_send_report is less than vendor recommended 60ms, so it failed to complete its power state transition, ignored i2c_hid_set_or_send_report and is still operating in legacy mouse mode, and therefore it gives unsupported input reports. This change updates the quirk for the device to specifies a 60ms post-setpower-delay-ms.
