Udev automounting for usb drives

Question

I am using the howto from the wiki to setup udev rules, so that my usb drives automount to /media/.
I have run into a snag though. My ipod shuffles and one of my thumbdrives go to /dev/sdc (with no number). But, the udev rules are looking for them to have numbers. I was wondering if there was a way to alter the current rules to also automount those devices that only have the main partition.
My ruleset:
KERNEL=="sd[c-z]", NAME="%k", SYMLINK+="usb%m", GROUP="users", OPTIONS="last_rule"
ACTION=="add", KERNEL=="sd[c-z][0-9]", SYMLINK+="usb%n", GROUP="users", NAME="%k"
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/mkdir -p /medimediasb%n"
ACTION=="add", KERNEL=="sd[c-z][0-9]", PROGRAM=="/lib/udev/vol_id -t %N", RESULT=="vfat", RUN+="/bin/mount -t vfat -o rw,noauto,flush,quiet,nodev,nosuid,noexec,noatime,dmask=000,fmask=111 /dev/%k /media/usb%n", OPTIONS="last_rule"
ACTION=="add", KERNEL=="sd[c-z][0-9]", RUN+="/bin/mount -t auto -o rw,noauto,sync,dirsync,noexec,nodev,noatime /dev/%k /media/usb%n", OPTIONS="last_rule"
ACTION=="remove", KERNEL=="sd[c-z][0-9]", RUN+="/bin/umount -l /media/usb%n"
ACTION=="remove", KERNEL=="sd[c-z][0-9]", RUN+="/bin/rmdir /media/usb%n", OPTIONS="last_rule"
Thanks!

I think that device sd? without sd?1 isn't correctly partitioned, or is it? All my usb pens have sd?1 on them, I never tried making filesystem on the physical device itself. I don't know, but at least, if you want to make special rule for one particular device, try this:
I mount my usb devices using this rule:
KERNEL=="sd?1", ATTRS{vendor}=="Corsair", ATTRS{model}=="Flash Voyager", NAME="%k", SYMLINK+="voyager"
ACTION=="add", KERNEL=="sd?1", ATTRS{vendor}=="Corsair", ATTRS{model}=="Flash Voyager", RUN+="/bin/mkdir /mnt/voyager"
ACTION=="add", KERNEL=="sd?1", ATTRS{vendor}=="Corsair", ATTRS{model}=="Flash Voyager", RUN+="/bin/mount -t vfat -o sync,flush,uid=1000,gid=100 /dev/voyager /mnt/voyager"
ACTION=="remove", KERNEL=="sd?1", ENV{ID_VENDOR}=="Corsair", ENV{ID_MODEL}="Flash_Voyager", RUN+="/bin/umount /mnt/voyager"
ACTION=="remove", KERNEL=="sd?1", ENV{ID_VENDOR}=="Corsair", ENV{ID_MODEL}="Flash_Voyager", RUN+="/bin/rmdir /mnt/voyager"
KERNEL=="sd?1", ATTRS{vendor}=="WD", ATTRS{model}=="1600BEV External", NAME="%k", SYMLINK+="passport"
ACTION=="add", KERNEL=="sd?1", ATTRS{vendor}=="WD", ATTRS{model}=="1600BEV External", RUN+="/bin/mkdir /mnt/passport"
ACTION=="add", KERNEL=="sd?1", ATTRS{vendor}=="WD", ATTRS{model}=="1600BEV External", RUN+="/bin/mount -t vfat -o sync,flush,uid=1000,gid=100 /dev/passport /mnt/passport"
ACTION=="remove", KERNEL=="sd?1", ENV{ID_VENDOR}=="WD", ENV{ID_MODEL}="1600BEV_External", RUN+="/bin/umount /mnt/passport"
ACTION=="remove", KERNEL=="sd?1", ENV{ID_VENDOR}=="WD", ENV{ID_MODEL}="1600BEV_External", RUN+="/bin/rmdir /mnt/passport"
I execute these actions based on device name - ATTRS{vendor}=="Corsair", ATTRS{model}=="Flash Voyager".
I used Writing udev rules guide, which explains how can you find devices properties and what udev events are triggered by plugging in usb pens for example.
Similary, you can use this approach for the problematic device and keep old match pattern sd[c-z][0-9] for other devices.
