I personally have never encounderd your problem, but i did a search on 
google.com/linux and found the following mail, it represents your problem in 
many ways, it also has a solution suggested as well.

usb-storage

[Luca T.]

Hello,
i would like to understand how hotplugging works, i did some experiments 
but without success.
If i did understand well, when i connect an usb-disk the script 
/etc/hotplug/usb/usb-storage should be fired... but this doesn't seem to 
happen.
I put a line inside it ( echo "test" >/tmp/test ) but the file is never 
created when i plug or unplug my usb-disk.
Why?

Thank you,
  Luca

This could be a configuration problem. Udev release 21, sysfs should be
mounted, udev rules in /etc/udev/udev.rules etc. Also, a valid rule in
udev.rules which would program your usb-storage device.

I was seeing the same problem but as I installed the above programs, it
went away.

Hmmm,
i don't have this udev thing nor sysfs mounted (i believe, not sure).
(Btw, i am running Mandrake 9.2)
So... i do not have udev nor sysfs but still, when i plug my usb-webcam, 
a new icon appears on my desktop. This means that in some way mandrake 
is doing it. I just want to understand how this is happening to make my 
custom scripts run instead.
Since i have /etc/hotplug i thought this was how.
Any idea?

Thanx,
   Luca

What kernel are you using?

On 2.4 that script would only be run when the driver is first loaded.
When the device is removed, the driver is never unloaded.

Re: usb-storage

[Luca T.]

Ok,
as Greg suggested the script is fired only the first time an usb-disk is 
plugged in.
I verified this by unloading the usb-storage kernel module and then 
plugging in an usb-disk. The script has been executed correctly.
Now, i need a way to detect when an usb-disk is plugged in and out, not 
only the first time, but everytime this happens.
I noticed that not only the usb-storage module isn't unloaded when the 
usb-disk is removed but it also leaves the device-file (for instance 
/dev/sda). So i have no way to know when the disk is removed :(

Any idea that could help me?

Thank you again,
   Luca

You will get a scsi event every time this happens, but this is only in
the 2.6 kernel.  2.4 does not support this.

Only udev manages the /dev entries, unless you are using devfs.  I'm
guessing you aren't using udev or devfs?  If so, the device nodes are
always there.

Hope this helps,

I'm using devfs, the device-files are dinamically created and removed... 
beside for the usb-disks, they are dinamically created, but not removed 
once the device has been unplugged :(

Then go bug the devfs developers :)

At least with recent hotplug packages user mode drivers are loaded even 
if kernel module is loaded or not, in 2.4 and 2.6.
