After testing automation all day, the system encounters an error and the automation stops.  
The error had occurred after about 6 hours or more.

I used the Saleae logic pro 16.  
below infomations are error code and my python code.

@ukjaeyu Sorry to hear about this! The formatting of the Python script gets pretty messy when posted directly as text.

Can you send over your .py Python file? We would be happy to take a look once you send that over.

@ukjaeyu Thanks for sending that over. First, I’d like to share our general guidelines for automating long captures below for quick reference.

> **[Automating Long Overnight Captures](https://support.saleae.com/faq/technical-faq/automate-long-captures)**

Next, with regards to your Python script, I’m unable to run it due to some missing dependencies. Based on the error reports you shared however, it looks like automation API loses connection with the software during the recording since the software likely crashed.

Can you share more details of the issue below?

- Can you confirm the exact behavior of the crashes you are seeing? For example, does the software crash when the error occurs? What happens after it crashes?
- Can you provide a high level summary of how your script operates? It looks your automation script simply performs a single 60 second captures. How many 60 seconds captures do you perform, and do you call your automation script multiple times?

If the software crashes, your next attempt at running your script will fail since the software needs to be running for `automation.Manager.connect(port=10430)` to work properly.

One workaround for this may be to use `with automation.Manager.launch() as manager:` to launch the software instead of connecting to a running session of the software. The software will need to be closed before running it, and the software will automatically close itself when the script is complete.

That way, if any crashes occur during the capture, the next call of the script will simply re-launch the software.

I think that this issue.

[Error Message: ReadTimeout - Saleae Support](https://support.saleae.com/troubleshooting/device-not-able-to-keep-up)

Solution :

1. device management → USB Controllers → Power mangement → disable : Allow the computer to turn of this devices to save power

2. click mouse periodic.

@timreyes After we’ve setted the disabling of our PC’s USB host controller power saving feature, The issue is occured again.  
Now, we are testing . We add the code of the mouse click one times, after waveform capture 1 cycle.

@ukjaeyu When you say that the issue is occurring again, are you saying that you are getting [ReadTimeout errors](https://support.saleae.com/troubleshooting/device-not-able-to-keep-up) that are causing your automation script to stop? Is this the main issue you are looking to solve?

If so, can you share the results of all of the troubleshooting steps in our ReadTimeout support article linked above? This will help us determine the source of the ReadTimeout errors (whether it’s an issue with USB bandwidth, your USB cable, Logic hardware, PC, or something else).

Please also share the information requested under the “Contacting Support for Additional Help” section.
