Just a quick note; I was using some udev rules similar to what Ken
posted above and found that they suddenly stopped working a little while
ago.  I finally got around to tracking down the problem yesterday and
found that the syntax of the udev rules (under Debian sid) has now
changed slightly; the KERNEL and SYSFS _tests_ now require "==" as the
operator instead of "="; the SYMLINK and NAME _assignments_ still use a
single "=" sign.

To make this more clear, here's what my rules look like now:

    mattrope@hades:~$ cat /etc/udev/rules.d/060_local.rules 
    # Local udev rules

    # Iomega USB hard drive
    BUS=="usb", KERNEL=="sd?1", SYSFS{product}=="Iomega HDD USB 2.0 Drive", NAME="%k", SYMLINK="usbhd"

    # Neuros MP3 player
    BUS=="usb", KERNEL=="sd?1", SYSFS{product}=="NEUROS Digital Audio Device", NAME="%k", SYMLINK="neuros"

    # Picture Card reader
    BUS=="usb", KERNEL=="sd?1", SYSFS{product}=="Flash Reader", NAME="%k", SYMLINK="piccard"

Unfortunately I wasn't paying close enough attention to say exactly what
version of udev the syntax changed in; I'm not sure if the change has
propagated to Debian testing yet or whether it's present in other
distributions, but I figured I should post this for future reference in
case anybody else runs across this issue.
