it's the hotplug (and alike) tasks to give the good right on the files according to the rules you've given it. Using suid or chown is a bad temp. hack. The long term is to generate an according. For example, look at SANE (scanners) and its libusbscanner (generally found in /etc/hotplug/usb/). Look the hotplug* dirs in the link below: http://cvs.alioth.debian.org/cgi-bin/cvsweb.cgi/sane-backends/tools/?cvsroot=sane > This is one thing which I want to avoid and therefore this time I selected > hiddev to program to.

IMHO (but Vojtech and others might have a different point of view), the usb (and hid) stack in Linux fits well for basic needs, ie input (keyb, mice, remote and joystick). More complex things have to go to userland, like SANE and NUT (UPS devices) have done. There are no need to put too much complexity in kernel, thus making it less reliable... But as you said, your device and need might match hiddev...
