So much for the rules in

Did it. Upon reboot, I had /dev/external_hd and /dev/external_hd1, but
only /dev/plextor_memstick (i.e., no mountable /dev/plextor_memstick1).
I unplugged the stick and turned off the HD case. I plugged back the
stick. Now /dev/plextor_memstick and /dev/plextor_memstick1 exist, as
they should. I turned the case on. Well, no /dev/external_hd...
Moreover:
$ systool -vb scsi | grep vendor
vendor = "PLEXTOR "
No external disk...
$ udevinfo -a -p $(udevinfo -q path -n /dev/sda)
no record for 'sda' in database
(...)
The same for sdb...
(There's something very wrong either with me or with udev. I'm ready to
accept the former, but I still remember when devfs went out, one year or
so ago, and my USB scanner stopped working.)
