hotplug problems

[Lawrence MacIntyre]

Hi:

I'm trying to write some code to use a SecureID 800 USB smart card.  I
can't seem to get the udev rules to work.  I have two rules that I think
should trigger when I plug the card in, but neither of them appears to
work.  The rules are in /etc/udev/rules.d/86-pcscd_ccid.rules and here
are the rules:

# If not USB, go away.
BUS!="usb*", GOTO="pcscd_ccid_rules_end"

# If not adding the device, go away.
ACTION!="add", GOTO="pcscd_ccid_rules_end"

# generic CCID device
SYSFS{bInterfaceClass}="0b", RUN+="/usr/sbin/pcscd --hotplug"

# sid800.txt
SYSFS{idVendor}="15e1", SYSFS{idProduct}="2007", RUN+="/usr/sbin/pcscd
--hotplug"

# All done
LABEL="pcscd_ccid_rules_end"

From running udevmonitor, here's what happens when I plug the device in
and remove it.

UEVENT[1178631737.409199]

UDEV  [1178631746.270250] add@/class/usb_device/usbdev1.12

If I dig through sysfs, I can find the device, but it's not always in
the same directory.

So I see that the idProduct, idVendor, and bInterfaceClass match the
rules, but they don't run the pcscd --hotplug command.  I have a program
listening for the pcscd --hotplug command, so I know that the command
isn't run.  Does anyone have any suggestions?
