Hi,

I'm using linux 2.6.11 on an ARM AT91RM9200 with hotplug-ng-001. On hotplug event, hotplug invokes a script called 99-usb2serial.hotplug as hig priority process. Is it possible to avoid this and instead run the script in normal priority?

regards,
Andreas

Add a setpriority(2) call to hotplug.c after the fork before the exec(3) of the child. Or try to use nice(1) in your script.
