You're suggesting that the RUN clause be
RUN+="pmount /dev/PNY &"
right?

The PNY stick mentioned runs very nicely on a machine at work. The
environment there is Ubuntu (as guest OS) running in VMWare on
WinXP (as host OS). Automounting works very nicely.
The slowness is true of several USB sticks.
Re: [gentoo-user] flash drive mounting is very slow
"usb verbose debug" in the kernel? - check dmesg. Mine are always slow
to mount if this is on.

To state the obvious ... have you tried it on a different USB port, a
different PC and finally a different OS?
I've had a USB stick failing recently and there was a mechanical (contact)
problem. So a process of elimination would at least do away with physical
level problems and indirectly confirm if there is something wrong with your
system.

Could the delay be caused by something else is fstab trying to mount
and failing? Try with mount /dev/PNY instead of mount -a.
Even better use pmount /dev/PNY.
Either way, you should run the command with & because udev blocks while
running commands.

As background information, in /etc/udev/rules.d/10-local.rules is:
KERNEL=="sd*1", ATTRS{manufacturer}=="PNY", SYMLINK+="PNY", RUN+="/bin/mount
-a"
and in /etc/fstab is:
/dev/PNY /mnt/pny vfat rw,nosuid,auto 0 0
The kernel messages in /var/log/messages for this period of time are in
the attached file (to avoid line wrapping by mail clients).
Any thoughts on why it takes so long and how I can speed up
recognition?
Ideas for enabling more messages (from udev, the kernel, etc) to see
what's happening would also be helpful.
TIA,

Just out of curiosity, have you tried it with no entry in fstab? I
don't have a entry for any of those in my fstab and it mounts in just a
few seconds.
Just a thought.
