I'm trying to write a rule that detects the unplugging of a particular
USB device and unloads the kernel module when that happens. The
reason is that the module appears to be buggy in that if the device is
reconnected without first unloading the module, the module hangs and
the device is not activated. At this point even forcibly unloading
the module makes no difference.
The device is a MultiTech GSM modem. The udevinfo used to build the
rule is pasted below. Here is the rule I've created (and installed in
/etc/udev/rules.d/85-mts_gsm_3410_remove.rules):
SUBSYSTEMS="usb", ACTION="remove", ATTRS{idVendor}="06e0",
ATTRS{idProduct}="f111", RUN+="modprobe -r ti_usb_3410_5052"
For testing purposes, I changed the modprobe to "echo hello from
ti_usb_remove >> /tmp/udev.works"
udevtest seems to indicate that the rule works:
# udevtest --action=remove
/devices/pci0000:00/0000:00:1d.3/usb4/4-1/4-1:2.0/ttyUSB0 | grep -v
^parse_file
[:snipped udevtest explanation:]
import_uevent_var: import into environment: 'DRIVER=ti_usb_3410_5052_1'
udevtest: looking at device
'/devices/pci0000:00/0000:00:1d.3/usb4/4-1/4-1:2.0/ttyUSB0' from
subsystem 'usb-serial'
udevtest: run: '/bin/sh -c 'echo 2 >
/sys/devices/pci0000:00/0000:00:1d.3/usb4/4-1/4-1:2.0/ttyUSB0/device/bConfigurationValue''
udevtest: run: 'echo hello from ti_usb_remove >> /tmp/udev.works'
udevtest: run: 'socket:/org/kernel/udev/monitor'
However if I actually unplug the device, /tmp/udev.works doesn't show
up. On the off chance that my kernel doesn't support inotify, I also
tried running "udevcontrol reload_rules". Still failed. The output
of udevmonitor, captured while unplugging the device, is pasted below.
For giggles, I also tried running a "logger hello" command instead of
the echo. Does not appear to run.
Any idea what I'm doing wrong?
Thanks!

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

ATTR won't work on a real remove, because the sysfs files are removed
before udev processes the event.
Apparently you can change the match to ACTION="add" and set
ENV{REMOVE_CMD}="modprobe -r ti_usb_3410_5052" instead. This feature
was recently mentioned here
<http://article.gmane.org/gmane.linux.hotplug.devel/14221>.
I don't know when REMOVE_CMD was added to the rules. If your rules are
too old, you should be able implement it yourself. It is a really
simple idea, you just need another rule to run the command on remove.
ACTION="remove", ENV{REMOVE_CMD}="?*", RUN+="$env{REMOVE_CMD}"
Oh, and this is a pretty major bug in the module, please make sure it
has been reported to the appropriate people :-).

My udev is, indeed, too old (version 117), so I implemented a similar technique:
SUBSYSTEMS="usb", ACTION="add", SYSFS{idVendor}="06e0",
SYSFS{idProduct}="f111", ENV{REMOVE_CMD}="/usr/bin/logger GOODBYE"
ACTION="remove", ENV{REMOVE_CMD}!="", RUN+="$env{REMOVE_CMD}"
That seems to be working. The problem I'm encountering now is that it
seems there are several "remove" actions called during initialization
of the device. If I swap in the "modprobe -r" command described in an
earlier email, it unloads the driver for the device before it even
finishes initializing.
Below I've attached a sample syslog snippet showing the many "GOODBYE"
messages logged when I plug in the deivce. Also I've attached the
output of "udevmonitor --env". For good measure, I've also thrown the
output of "udevinfo -a -n /dev/ttyUSB0" at the end.
Any idea how I can get my RUN command to only execute when I'm
actually unplugging the device?
Thanks!

Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Sorry I don't understand the behaviour of this device. You sound
stuck, I guess I can suggest a hack.
Create a script to run in place of "modprobe -r". Start with "sleep
1" or so, to give the driver time to initialize. Check that the
ttyUSB device node no longer exists. Only then let it do "modprobe
-r".

That makes two of us.

Worth a shot. Thanks!
