wait_for_sysfs:

main: run: '/lib/udev/openct_usb'

main: run: 'socket:/org/kernel/udev/monitor'

looks ok to me.

yes, udevtest is always fine.

that works as well.

that solved the problem. small delay, but now the
plugin works all the time. will add that to openct.
(or rather remove the "sleep 1" I already have in my
script to "wait" for the device file and add the sleep 1 as
udev rule instead).

btw: if this get fixed so the "sleep 1" becomes obsolete one day - is there 
some rule etc. to wait for the /proc/bus/usb or /dev/bus/usb devices, so I
won't need an arbitrary sleep for that either?

Thanks for your help.
