What I'm after allows shutter control with a mouse click - any other
controls would be a bonus.

Linux will see the camera as a USB device and let you grab the
existing files on there, to force the camera to take pictures in "tethered"
mode check out "gphoto2", if it supports your camera, then it could
help :-

List files with gphoto2 --camera="Oregon Scientific DShot III" -L

Get all files with gphoto2 --camera="Oregon Scientific DShot III" -P

Get numbered files with gphoto2 --camera="Oregon Scientific DShot III" -p 5-7

Delete all files with gphoto2 --camera="Oregon Scientific DShot III" -D

Delete numbered files with gphoto2 --camera="Oregon Scientific DShot III" -d 1-9

*** Force capture of picture from PC, stored on camera with
gphoto2 --camera="Oregon Scientific DShot III" --capture-image ****

Capture filenames can be set with
--filename=`date +"%Y%m%d_%H%M%S".jpg`

This works with some cameras, not others, depends on support from the
manufacturer to provide such a useful facility, and then on the driver
writer!

So a combination of force capture, get file, delete file in sequence would
fetch the pics straight over to the PC.
