Re-programming SenseCAP: not showing up as /dev/cu.usbserial-xxxx anymore

[ooktown]

If this helps, I'm on a Mac and ran a dmesg command. It looks like there’s a USB failure to create a device, but I’m not sure what I’m looking at…

Here's the output:

Let me know if you have ideas on what to do to reprogram the SenseCAP Indicator. Thanks!

This is a very strange phenomenon. It seems that the USB enumeration failed.

Thanks for your response!

Is there anything I can try to help debug the cause of the failure?

@ooktown Thank you for providing the additional debugging information on the USB enumeration failure with your SenseCAP. I have looked into the details you provided but unfortunately we are still unable to determine the specific cause of the behavior.

If you are no longer experiencing this problem when trying to reprogram the SenseCAP, or you do not require further troubleshooting, I will go ahead and close out this issue for now. Please feel free to reopen if you run into this again in the future, and can provide new logs or debugging steps that may help track down the problem.
