why don't my rule work anymore

why don't my rule work anymore

[Martin Lorenz]

since my last upgrade to udev 0.066-1 (debian unstable)
the rule I used for almost a year now dosen't work anymore.

SYSFS{serial}="XXXXXXX", NAME="cruzer%n"

used to create /dev/cruzer and /dev/cruzer1
for my usb thumb drive

now I only get /dev/cruzer with this rule 
when I deactivate it completely I get /dev/uba and /dev /uba1
with the rule also /dev/uba1 is omitted.

dmesg says so:
usb 3-3: new high speed USB device using ehci_hcd and address 21
ub(3.21): GetMaxLUN returned 0, using 1 LUNs
 uba: uba1
usb 3-3: USB disconnect, address 21

udevmonitor
udevmonitor prints received from the kernel [UEVENT] and after
the udev processing, the event which udev [UDEV] has generated

That should better be '='. But the syntax is not enforced for the
SYSFS key and '=' should also work.

Care to try:
  udevtest /block/uba block
  udevtest /block/uba/uba1 block

and see what it prints.

but it did the trick
definitely works again now that I replaced the '=' with '='

and the same with the '=' rule:
...weeeeeelll
I am positively sure that changing the rules from '=' to '=' was the
only thing I did, but now it works again also with '=' in place instead
of '='

I have no idea what else could have happened.
just a few more hours of uptime
nothing else installed, nothing deinstalled nothing configured
only some work done...

those are the things I hate most. having a problem sloved and not
knowing how...

thnx for you help
greets 
mlo
