The linux-hotplug-devel mailing list is best place for questions about
udev, not lkml...

Try changing BUS="usb" to BUS="scsi".  Also make sure that the model
file doesn't contain any trailing spaces.  That's a very common thing on
usb devices.

And you are trying to match up 2 files, right now udev only supports 1,
so the last one (model) is used.  The vendor rule there is ignored.

There is also a problem with udev beating the kernel.  It can easily get
the hotplug event before the kernel has created the sysfs file.  I'm
currently working on fixing this in udev, should have it done by the
next release.  You can tell if you are seeing this race by just running
the test.block script in the test directory in udev.  If your device
node is created properly with that script, but not when you plug the
device in, you have that problem.

And people tried to tell us that the hotplug interface was slow without
ever testing it out...

Hope this helps,
