Yes, this is exactly what I have in 50-udev-default.rules.

I tried that, and now the rule wouldn't even apply. It seems that DEVTYPE=="usb_device" is not handled correctly. If I remove this condition, the rule is applied. I have one file 99-sbig.rules which has the following:
SUBSYSTEM=="usb", ACTION=="add", SYSFS{idVendor}=="0d97", SYSFS{idProduct}=="0001", ENV{DEVTYPE}=="usb_device", \
RUN+="/sbin/fxload -I /lib/firmware/sbigucam.hex -D $env{DEVNAME}"
I don't understand why DEVTYPE is not caught, I ran udev monitor and got the following when I plugged my USB cam:

If I remove the ENV{DEVTYPE}=="usb_device" from the rule, I can use $env{DEVICE} since it's the closest thing to what I need, albeit it's under /proc and that doesn't work, I need /dev/bus/usb/XXX/YYY. Of course, DEVNAME evaluates to /dev/usbdev1.25_ep00 which is useless.
At any rate, here is what I get in /var/log/messages

Notice that despite the default rule in 50-udev-default.rules (NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}"), the log says:
udev_rules_get_name: no node name set, will use kernel name 'usbdev1.25_ep00'
Btw, I get the same results in Fedora 9 and openSUSE 11, so it doesn't appear to be distro-specific.
Any insights appreciated!
Cheers,
Jasem
