usb + sysfs + udev problems once more

[Andreas Jellinghaus <aj@leogic.com>]

I thought to try the latest ubuntu beta version to see if
kernel + usb + sysfs + udev work as expected, but they don't.
the kernel is 2.6.22-rc, udev is 111-0ubuntu5. 

I'm posting here, as I guess this is not distribution specific.

the problem I see is this: when I plugin my usb smart card reader,
I see a number of events using "udevmonitor --kernel --environment".
of these I'm interested in these two:

UEVENT[1182947366.505829] add      /devices/pci0000:00/0000:00:1d.2/usb3/3-1 
(usb)
ACTION­d
DEVPATH=/devices/pci0000:00/0000:00:1d.2/usb3/3-1
SUBSYSTEM=usb
SEQNUM%49
MAJOR\x189
MINOR%8
DEVTYPE=usb_device
PHYSDEVBUS=usb
DEVICE=/proc/bus/usb/003/003
PRODUCTŽ6/3438/100
TYPE=0/0/0
BUSNUM\03
DEVNUM\03


and


UEVENT[1182947366.505908] 
add      /devices/pci0000:00/0000:00:1d.2/usb3/3-1/3-1:1.0 (usb)
ACTION­d
DEVPATH=/devices/pci0000:00/0000:00:1d.2/usb3/3-1/3-1:1.0
SUBSYSTEM=usb
SEQNUM%51
DEVTYPE=usb_interface
PHYSDEVBUS=usb
INTERFACE\x11/0/0
MODALIAS=usb:v08E6p3438d0100dc00dsc00dp00ic0Bisc00ip00


the first is nice, as it has the DEVICE info. I need that one.
however, only the second is matched by the udev rule:
SYSFS{bInterfaceClass}="0b", SYSFS{bInterfaceSubClass}="00", 
SYSFS{bInterfaceProtocol}="00" RUN+="/lib/udev/openct_usb"

so in the end my script is called only once, but without DEVICE.

how do I fix this?

or is this a kernel / sysfs problem that cannot be worked around?

and is there any chance udev will create events
for the /dev/bus/usb/ device files it creates?

thanks for your help.

Regards, Andreas
