For anyone experiencing USB mass storage problems under Slackware10.2...

Interesting.  I run Slackware 10.2, but never had this problem.  You could
also just disable udev altogether.  Actually, I seem to recall that udev was
turned off by default in 10.2, apparently, because it was causing problems
for some users.  To check if it is on or off, see if /etc/rc.d/rc.udev has
execute permission for root.  If it does, it's on, otherwise, it's off.
