Changeing this to

blackbox:~# cat /etc/udev/rules.d/z61_sispmctl.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="04b4", ATTRS{idProduct}=="fd13", 
GROUP="sispmctl", MODE="0664"
blackbox:~# 

fixed the problem.


I am wondering if sispmctl should include an udev rule in the Debian package?

Thanks,
Rainer
