I agree with the approach, although reading an article that outlined how it works these days in F10 would be better. Where would I start looking for how a comparable USB device is handled ? I looked in /etc/udev/rules.d, but I don't see any specific handlers for devices and the hal-rules.d file has this: # pass all events to the HAL daemon RUN+="socket:/org/freedesktop/hal/udev_event" Have things changed ? -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

It used to be that you edited or created a new rule in /etc/udev/rules.d. The lower the number the earlier in the process the rule got looked at. However, it appears to me that things have changed. I no longer see explicit USB rules in that directory and the hal.rules file has this: # pass all events to the HAL daemon RUN+="socket:/org/freedesktop/hal/udev_event" I set this device up a couple years ago and now I don't remember how. Or things have changed. -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

One way is to create a udev rule that sets the permission for the
device. You may also want to create a symlink to a consistant device
name at the same time.
If there isn't a device created for it, it gets a bit more
interesting. I have a small script that I call from the udev rule
that sets the permissions for the specific device in /proc/bus/usb.
I actually wrote it for use with VirtualBox, but it should work for you.
# Rules for VirtualBox USB devices.
ACTION!="add",SUBSYSTEM!="usb", GOTO="vbox_rules_end"
# eBookwise eBook reader.
ATTR{idVendor}=="0993", ATTR{idProduct}=="0002",
run="/lib/udev/set-usb-group %s{uevent}"
LABEL="vbox_rules_end"
#! /bin/sh
ret=false
if [ "$DEVICE" != "" ]; then
if [ -e $DEVICE ]; then
chgrp vboxusers $DEVICE && \
chmod g+rw $DEVICE && \
logger udev/set-usb-group: $(ls -l $DEVICE)
ret=true
fi
fi
The group is hard coded in the script, and it only give group
permissions, but that is easy to change. One of these days I will
get around to cleaning it up, and let it get the
user/group/permissions as input.

I always wonder about how to fiddle hal rules. I have found hal rules in the past I wanted to change (like putting different permissions on the device file it creates), but I know if I change the actual rule file, then the next time there is a hal update that file will get updated and my changes will disappear. Is there some magic way to properly define hal rules that override existing rules in the installed system files?
