Hello,
I want to call a script after I plugged my USB scanner. I use udev for this by
adding a rule
rd at blackbox:/etc/udev/rules.d$ cat z_local.rules
SYSFS{idVendor}=="1606", SYSFS{idProduct}=="0010", MODE="0664",
GROUP="scanner", NAME="umax%n", RUN+="/usr/local/bin/umax1220u start",
rd at blackbox:/etc/udev/rules.d$
This calls then the umax1220u script:
rd at blackbox:/usr/local/bin$ cat umax1220u
#!/bin/sh
set -vx
# example for a DEVICE: /proc/bus/usb/001/004
echo umax1220u $DEVICE $* >> /tmp/usb.log
export >> /tmp/usb.log
ACTION=$1
# if [ -z $DEVICE ]; then exit 0; fi
case $ACTION in
start)
echo "UMAX 1220u scanner added"
# DEV=umax1220u:libusb:`echo $DEVICE|cut -d / -f 5`:`echo $DEVICE|
cut -d / -f 6`
DEV=`scanimage -L|cut -f 2 -d \\\`|cut -f1 -d \'`
echo started: $DEV >> /tmp/usb.log
# example for a DEV umax1220u:libusb:001:006
(sleep 20
&& /usr/bin/scanimage --lamp-off --device=$DEV --dont-scan) &
;;
stop)
echo "UMAX 1220u scanner removed"
;;
esac
rd at blackbox:/usr/local/bin$
When I plug my scanner with this config, it seems an infinite number of
umax1220u scripts are started in a sequence (i.e. not in parallel, when one
is completed the next one starts).
Initial analysis shows that scanimage causes in syslog
Apr 22 22:07:48 blackbox kernel: ppdev0: registered pardevice
Apr 22 22:07:48 blackbox kernel: ppdev0: unregistered pardevice
Apr 22 22:07:50 blackbox kernel: ppdev0: registered pardevice
Apr 22 22:07:50 blackbox kernel: ppdev0: unregistered pardevice
This might then kick off another umax1220u via udev (?). An this would then
loop.
Does anybody know how I could get rid of this event?
Does anybody know a better way to get the script started which switches the
scanner lamp off?
Thanks,
Rainer
