/etc/hotplug/usb/libusbscanner, as shipped with Fedora Core 2, already
sets the ownership of the appropriate /proc/bus/usb/... file to the
"console" user. This works fine when a scanner is plugged in *after*
the user has logged on.
I've hacked /etc/hotplug/usb/libusbscanner to create a symbolic link
from /dev/usb/scanner-%sys%devices%pci%... to that /proc/bus/usb...
file. When the USB "insertion" is processed during system boot, the
symlink gets created. Then when a "console" user logs on, PAM follows
the symlink and sets the ownership of the /proc/bus/usb... file
appropriately.
All I want to do is run a script during the USB "remove" event to get
rid of this symlink. Reading through /etc/hotplug/usb.agent, it looks
like I should be able to put a script in the location specified by the
${REMOVER} variable, but I've tried this and it never gets executed.
What do I need to do?
