I have not used that model, but had no problems accessing older ones and their DSLRs as USB storage devices. It may take a configuration change.
Great, thanks, that was it. But - it's already going to be Canon A550, especially as it has raw format support unlocked via a custom firmware. There's nothing clear about connectivity on the Nikon product page - http://imaging.nikon.com/products/imaging/lineup/digitalcamera/coolpix/l18/ - and A550 was listed in the apps' lists (Digikam, GPhoto...). Another point against the L18 was it not having an optical viewfinder, plus the LCD broke for a few buyers.
