BUS==scsi and I would also use SYMLINK=istick%n instead of NAME. I'd
also guess that the SYSFS{serial} is not the one of the stick, but four

This is a character device.
So, why doesn't my /dev/istick work?
I assume it has to do with that 'b' on /dev/sda1 and the 'c' on
/dev/istick
Yes.

This should be in /etc/udev/rules.d/10-local.rules, so it is processed
before the default rules, but that's not the problem here.
locutus linux # cat /etc/fstab
# Intelligent Stick flash drive (UDEV)
/dev/istick /mnt/istick vfat defaults,noauto,user,umask=000 0 0
locutus linux # ll /dev/istick
crw-rw-rw- 1 root root 21, 1 Jun 9 00:32 /dev/istick
locutus linux # mount /dev/istick
mount: /dev/istick is not a block device
That's because you are trying to mount the whole device, not the
partition.
locutus linux # ll /dev/sda1
brw-rw 1 root disk 8, 1 Jun 9 00:32 /dev/sda1
locutus linux # mount -t vfat /dev/sda1 /mnt/istick/
locutus linux # ls /mnt/istick/
MIDI Files pwsafe.key
Now you are mounting the partition.
So, why doesn't my /dev/istick work?
I assume it has to do with that 'b' on /dev/sda1 and the 'c'
on /dev/istick
Yes, it's not a block device. Change the NAME part of the rule to
NAME=istick%n and mount /dev/istick1. Or just set up a rule to match
the partition. This is the sort of thing I use for a USB stick
BUS==usb, KERNEL==sd?1, SYSFS{idProduct}==0845, SYSFS{idVendor}==08ec,
NAME=gigabyte, SYMLINK=%k usb/gigabyte
I don't use fstab, but let KDE/HAL/pmount mount it on /media/gigabyte.
But I could put /dev/gigabyte in fstab if I didn't want automounting.

Even the whole device should be a block device, shouldn't it? And if it had
a filesystem, you could even mount it, having one partition is as good as
having no partition, at least for Linux.
BUS==usb, KERNEL==sd?1, SYSFS{idProduct}==0845,
SYSFS{idVendor}==08ec, NAME=gigabyte, SYMLINK=%k usb/gigabyte
OK, here is what I do :-)
BUS==scsi, KERNEL==sd*, SYSFS{model}==HardDrive ,
SYSFS{rev}==1.11, SYSFS{vendor}==32MB, SYMLINK=usb/stick%n
This will give me nodes for the device itself and its partitions.

Yes it should, it's podd that is appears as a character device.

It's not the same. A filesystem on a single partition filling the device
is not the same as a filesystem on the device itself. Both are possible,
and mountable, but not at the same time. I've just checked with with a
single partition device to be sure, it didn't work.

I do that for some drives, but my USB sticks are always a single
partition, so I give the name to the partition not the device. I also set
NAME and put %k in SYMLINK, because pmount uses the name to create the
directory in /media, and I want the device mounted
at /media/somethingmeaningful, not /media/sdxn.

The device has major number 21, and char device 21 is SCSI generic, not SCSI
disk (which is block device 8, see below). This may come from not having
KERNEL==sd* in your rule.

RE: [gentoo-user] help with UDEV and USB flash drive
Thanks everybody that was the trick. I settled upon this:
BUS==usb, KERNEL==sd?1, SYSFS{idVendor}==0ef5,
SYSFS{idProduct}==2202, SYMLINK=istick%n, MODE=0666
And for my /etc/fstab entry:
/dev/istick1 /mnt/istick vfat defaults,noauto,user,umask=000 0 0
Now the second part of this. SOMETIMES, when I plug the stick in (I assume
that's when it happens), KDE gives me a nice little window to view the files
or take no action. But it's not consistent?! What triggers that 'event', and
how can I make it happen all the time?
Also related, is there an easy way to make this stick auto un/mount upon
removal/insertion respectively?
I tried taking out the 'noauto' in fstab, but that didn't do it.
I saw some web search results, but most of them feel outdated, or for other
distros.

One problem with this. Udev will apply all matching rules until it
finds one with a NAME entry. So you probably want MODE:=0666 to
prevent any later rules from overwriting your mode.
