Using a card reader can be a problem, depending on the camera. As someone
who's owned several, I can tell you that MANY of these cameras, even the
good ones, have very flimsy doors and hinges that cover the battery and
memory card slots. Open those doors 40-50 times over several months, and
trust me, you'll eventually break it. It's best to keep the card installed
and then forget about it, treat it as integral memory. Granted, situation
or design might thwart your efforts, but this is a big reason I don't use
card readers as a rule.
As far as the specific problem, I've never had an issue w/ a digital camera
AT LEAST being recognized as a removable drive. The only purpose for the
installation of camera specific drivers (at best I can tell) is to provide
camera-specific services. Frankly, I find most of this software AWFUL.
Olympus, Kodak, Canon, and the rest of them may build fine cameras, but when
it comes to PC software, most of it is pretty awful. So in most cases, I
don't even install the camera's driver or software. Either Windows
recognizes it as a digital camera, and thus I get the "generic" camera
wizard, which is FINE for most people, OR, worst case, it's just recognized
as a removable drive (similar to a USB pen drive). In that case, it merely
requires manipulation like any other files using Windows Explorer (CUT,
COPY, PASTE). In some cases, the digital camera may have to be configured
through its interface as a USB device before Windows will recognize it. I
use to have to do that w/ my old HP PhotoSmart camera.
