USB cpu utilization outbreak

Smth went wrong with cpu utilization.
Using rpi 4 with radarbox green stick. No changes in settengs were made il last 5 days.
Rebooted with no success
What could it be?

It looks like USB CPU utilization went up but overall CPU and memory utilization went down. Are you experiencing issues related to the increased USB CPU utilization?

I assume you have updated recently and causing the problem where lots other users discussed.
It’s a library issue. In the thread you will finde different solution.

sudo bash -c "$(wget -q -O - https://raw.githubusercontent.com/wiedehopf/graphs1090/master/install.sh)"

Then go to

or from rpi browser

Nothing special to download but a lot of work by @wiedehopf to modify the old script and support it :smiley:

The best part of modification from old script of J Prochazka to current script of @wiedehopf was to eliminate its dependency on “Web Portal”, and make it a stand-alone app. Good work by @wiedehopf, who has done other improvements/enhancements as well.
