I need to have higher prio because we lose ethercat frames on receiving because the ethercat master is running in a prio/Task context
higher than the irq's are handled.
This is what I know and I try to change.
So i check which is the usb iqr by
and then try to change the prio with:
sudo chrt -pf 70 62
But i fear this does not work because
does even show still the same prio for the usb irq
So maybe i'm totally wrong to do this that way?
