UDEV rule for uploading firmware

[berthold@xn--hllmanns-n4a.de (Berthold Höllmann)]

I try to fix a UDEV rule for uploading firmware for an USB audio
device. The tool madfuload has to get the device name in either the
DEVICE environment variable or via a command line switch. The original
rule as delivered with the program is:

ACTION="add", SUBSYSTEM="usb", DEVPATH="/*.0", ENV{PRODUCT}="763/2806/*", RUN+="/usr/local/sbin/madfuload -l -3 -f /usr/local/share/usb/maudio/ma006100.bin"

But this gives only 

madfuload: --device not given, and DEVICE not set

in /var/log/messages when I attach the device.

I tried a lot with the command line, even hardcoding the next
predictable device name, but always get

madfuload: cannot open '/dev/.tmp-0-0': No such device or address

or

madfuload: cannot open /dev/bus/usb/005/028: No such file or directory

even when a manual call with /dev/bus/usb/005/028 is successfull
afterwards.

The original rule file name is 42-madfuload.rules and I tried to
increase the leading number to get the rules applied later in the
chain, but no go.

With SuSE 10.1 I fixed the problem by reactivating the usbfs mount by
fixing the /etc/fstab, but with openSuSE 10.2 I only get

# mount -a
mount: mount point /proc/bus/usb does not exist

# pre SuSE 10.1
#usbfs                /proc/bus/usb        usbfs      noauto
#0 0
# SuSE 10.1
/dev/bus/usb         /proc/bus/usb        usbfs      defaults              0 0

Is there a way to fix this problem in udev, do I have to change my
fstab entry or do I have to switch to a different tool like HAL?

Thanks
Berthold
