With some help from Jeff Coppock (thanks!), I was able to get hotplug
to work with my Toshiba PDR-M71 digital camera. I am posting this
message in case anyone else runs into the same problem as me. First,
here's what I'm using and what I did to get it to work:
Linux kernel 2.4.20 (kernel-image-2.4.20-686 2.4.20-3)
hotplug 0.0.20020826-1
I had to edit /etc/hotplug/usb.rc and use the "uhci" module instead of
the "usb-uhci" module:
# NOTE: this prefers "uhci"; you may prefer "usb-uhci".
modprobe -q uhci >/dev/null 2>&1 || modprobe -q usb-uhci >/dev/null 2>&1
# modprobe -q usb-uhci >/dev/null 2>&1 || modprobe -q uhci >/dev/null 2>&1
Oh, another thing was that I had to enable support for USB in my CMOS
setup! I had forgotten that I had disabled it a long time ago when I
first set up the computer with Debian and Linux 2.2.
So with the above changes, I am now able to hook up the camera, turn
it on, and the following appears in /var/log/messages:

I can then type "mount /mnt/film" and access the pictures. I have the
following entry in /etc/fstab:
/dev/sdb1 /mnt/film vfat defaults,ro,user,noauto 0 0
(You might need to use sda1 instead; refer to your /var/log/messages).
Of course I had to first create the "film" subdirectory under /mnt as
suggested by Ole Aamot at http://www.aamot.org/ole/photography.html (I
didn't particular know where I should mount it, and his idea sounded
ok for now.)
Before I turn off the camera, I type "umount /mnt/film". Then I turn
it off and the following appears in /var/log/messages:
Jan 3 22:13:18 lorien kernel: usb.c: USB disconnect on device 00:07.2-2 address 2
I hope this is helpful,
Ken
P.S. I am not subscribed to this list.
P.P.S. The problem I ran into when using the default "usb-uhci" module
in hotplug is that the camera would seemingly be recognized but the
scsi support never materialized. In particular, the error message
"device set offline - command error recover failed" would appear:
Dec 29 15:02:36 lorien kernel: hub.c: new USB device 00:07.2-2, assigned address 2
