Well, it works. And not a bad little camera either, pretty sharp, low light is pretty excellent. No problems streaming at 640x480, although the fps can be a little low. I paid £16.99 for it from PC-World yesterday.
If you're thinking about getting the E2500 then don't! I bought that one first, and while it is a UVC camera, it's not fully compliant with the standard. Logitech have some dedication towards Linux, and list the various chipsets of the different models.

The procedure for getting the E3500 running with ZoneMinder is to install uvc_stream, and then to access it as remote source.
Installing UVC is a bit interesting, although once the procedure is established then it's not that bad at all.
These are the Debian 5.0 Lenny procedures. I'm running it with a Console only, as in, no Gnone, KDE, or X etc. Just a plain old 80x25 text screen.
This is all assuming that you've plugged the camera in, can see it via the lsusb and dmesg commands. Also /var/log/syslog will indicate that it's been plugged in and recognised.
1. Get the prerequisites installed :
apt-get install gcc subversion
2. Get UVC and make it :
mkdir /usr/local/src/uvc_streamer
cd /usr/local/src/uvc_streamer
cd uvc-streamer
make
cp ./uvc_stream /usr/local/bin
3. Now for the moment of truth :
chmod 777 /dev/video0
/usr/local/bin/uvc_stream -d /dev/video0 -b
4. You can check if it's running by going to port 8080 on the target machine, here my machine is a static 192.168.1.5 :

5. To make it launch automatically at boot, create the following file (and check it afterwards, third quote below containing cat) :
vi /etc/init.d/uvc_video0
#!/bin/sh
chmod 777 /dev/video0
/usr/local/bin/uvc_stream -d /dev/video0 -b
cat /etc/init.d/uvc_video0
6. And link that file to the same runlevel as ZM, but before ZM :
ln -s /etc/init.d/uvc_video0 /etc/rc2.d/S19uvc_video0
7. Finally, add it to the ZM Console, but as a remote camera, see the images, mine is already installed, setup, and detecting, so these images are just a guideline :
