Len, I've been investigating time-lapse photography lately. This
crowd has the interface information you might need to complete your
project. You might consider a second interface (LANC) for additional
control of your camera.

While I'm sure there a dll call you could use, the only way I've
found so far is to download a utility from MS (devcon.exe). This
tool is basically a command line version of "Device Manager" so it
can be used for much more than USB drives. If you do a Google
search, there a several people that have written C versions of this
same basic code so I imagine it wouldn't be too hard to write an
external for Rev.
As to using "the volumes" to get the drive letters, it does in fact
return a list of drive letters but doesn't tell you anything about
the drives (other than the letters) so I'm not sure how to match
them up.
Lastly, in Linux, I think you can just run the "mount" command and
it will return a list of mounted drives. If automount is running,
when you plugin a thumb drive it should be mounted and then show up
in the list.
My final problem, and this may be unique to me, is that I want to
leave a digital camera hooked up to a computer and be able to read
the photos out of it. The problem is that apparently digital
cameras (I've tried several) detect the connection to the computer
and turn themselves off until you unplug. I guess what I need is a
way to power down a USB port so the camera is fooled into thinking
that it has been disconnected. This may not be possible.
