 |
|
Hi!
Writing a universal USB-Storage hotplugging script I figured out that there seems to be a bug in usb.agent.
When plugging in an USB-Pen, the "add" event is generated and $REMOVER ist set in usb.agent via
| Code: |
...
#
# declare a REMOVER name that the add action can use to create a
# remover, or that the remove action can use to execute a remover.
#
if [ "$DEVPATH" != "" ]; then
# probably, 2.6.x
REMOVER=/var/run/usb/$(readlink -f $SYSFS/$DEVPATH | sed -e 's;/;%;g')
^^^^^ This DOES work when plugging in.
elif [ "$DEVICE" != "" ]; then
# 2.4.x?
REMOVER=/var/run/usb/$(echo $DEVICE | sed -e 's;/;%;g')
else
# should not happen?
REMOVER=/var/run/usb/$(echo "$INTERFACE/$PRODUCT/$TYPE" | sed -e 's;/;%;g')
fi
export REMOVER
...
|
but when unplugging readlink can not return anything because the /sys/devices.... does not exists anymore.
Is there already a solution for this?
Oh, I use hotplug 20040923 and hotplug-base 20040401 |

I submitted a bug-report to the developers, including the fix below:
| Code: |
#
# declare a REMOVER name that the add action can use to create a
# remover, or that the remove action can use to execute a remover.
#
if [ "$DEVPATH" != "" ]; then
# probably, 2.6.x
REMOVER=/var/run/usb/$(echo "$SYSFS$DEVPATH" | sed -e 's;/;%;g')
elif [ "$DEVICE" != "" ]; then
# 2.4.x?
REMOVER=/var/run/usb/$(echo $DEVICE | sed -e 's;/;%;g')
else
# should not happen?
REMOVER=/var/run/usb/$(echo "$INTERFACE/$PRODUCT/$TYPE" | sed -e 's;/;%;g')
fi
export REMOVER
