control_transfer returned error, index: 768, error: No data available, number: 61

参考
If control_transfer returned warnings only occur during launch and then stop, or only appear once or twice a minute after launch, then they can be safely ignored.
If the warnings continuously generate after launch then this can indicate that there is a serious communication problem wth the device.

用D435i有些报错是正常的，不影响使用。
