The code below regularly crashes, if I let it run for a couple of minutes. It never reached 10min so far. I’d like to run it for a couple of hours. Why could it be that the Device Setup fails? Any suggestion would be appreciated.

Code:  
#########################################################  
with automation.Manager.connect(port=10430) as manager:  
dev\_conf = automation.LogicDeviceConfiguration(  
enabled\_analog\_channels=[0],  
analog\_sample\_rate=625000,  
)  
cap\_conf = automation.CaptureConfiguration(  
capture\_mode=automation.TimedCaptureMode(duration\_seconds=T\_sample)  
)  
abs\_path = ‘C:\work\git\vinsontruck-python-tools\scripts\out\’  
with manager.start\_capture(device\_configuration=dev\_conf,  
capture\_configuration=cap\_conf) as capture:  
capture.wait()  
capture.export\_raw\_data\_csv(abs\_path, analog\_channels=[0])  
ntc\_dat = pd.read\_csv(abs\_path + ‘analog.csv’)  
ntc\_u\_arr = ntc\_dat[“Channel 0”].to\_numpy()  
u\_mean = np.mean(ntc\_u\_arr)  
u\_std = np.std(ntc\_u\_arr)  
return (u\_mean, u\_std)  
#########################################################

I am using windows 11, Python 3.8.6 in VS Code 194.0, Logic 2.4.14, Logic 8 hardware, USB cable directly connected to mainboard of laptop, I tried both laptop USB ports  
Thank you for your help

My guess would be you might be having some USB intermittent issues. Does it happen if PC stays ‘busy’ (i.e., actively using PC keyboard/mouse while script is running vs. console is essentially ‘idle’ other than the script?) Does the `Logic 2.exe` process hang/crash in Task Manager?

**Quick tips:**

- Make sure the Logic is only device on USB, if possible  
(no other USB devices connected/in use)
- Make sure PC is on AC vs. battery power  
(set on full/high performance, not battery/lower power optimized)
- Make sure USB port won’t go to sleep  
(Turn off all USB power saving options, so ‘always on’ and Windows won’t disable/power off port)
- Try the same script on a different PC (if possible, a different model) and see if you get the same result
