Hi Folks,
Posting this in case other folks accidently run into this. I was observing the Joulescope output to randomly “cut off” during testing and eventually found out it’s related to the fact that I had too many devices attached to my USB hub. The USB hub is self-powered, but with multiple devices attached seems like it was not able to supply enough current to my joulescope.
In any case, this was the symptom from the joulescope log under “Help”–>“View Logs”… search for “error”
ERROR:2021-08-13 09:26:18,450:device.py:378:joulescope.usb.winusb.device:endpoint halt 1: EndpointIn WinUsb_GetOverlappedResult fatal: [31] A device attached to the system is not functioning.
Thanks again Matt for the help
