I had a look at it, and it isn't much of a driver. (A lot of the
drivers I download, have comments or contain hints I can use. This
driver is about as naked as they get.)
ftp://download.sony.com/US/dvimag/USBDRVEN.EXE
One element of the driver, calls a standard Microsoft file (usb.inf),
so a system driver is being used in that case. They do that,
to handle the "composite" device your camera represents (camera could have
audio and video, two separate entries in the USB config info).
Other than that, one of the parts of the driver, seems to be intended
to allow you to capture a picture from the camera while the camera
is turned on. I don't expect that is what you're trying to do right
now. It almost looks like you should be able to contact the camera,
download the pictures, without that driver.
My guess would be, in light of the severe lack of details
in there, that the camera is set up as USB mass storage, and
if that were the case, it would automatically appear as a
hard drive entry. If that doesn't happen, perhaps the
media inside the camera, isn't formatted into a recognizable
file system ?
You can use UVCView, to verify the camera is detected on the USB port.
UVCView is a Microsoft program, no longer offered for download, so
you have to get it from somewhere else now.

You should be able to get VEN and DEV info from a plugged
in device. That program will also help you determine whether
the camera is alive at all or not.

You have to be a little careful with camera media. If the media
needs to be formatted, you should do that with the camera, rather
than from the computer end. The camera is best prepared, to
format its own media. Sometimes, doing it from the computer,
screws it up. Test with a spare blank piece of media, so you
don't overwrite the pictures currently stored.
Some cameras, require you to switch them into the appropriate
"mode", before they'll appear as a mass storage device. Other
cameras use MTP, a different protocol than USB Mass Storage.
And the system driver for that, used to be delivered with
Windows Media Player. MTP allows both the camera and the
computer, to be updating the media at the same time. While
with USB Mass Storage, only one agent can be accessing it
at a time.
http://en.wikipedia.org/wiki/Media_Transfer_Protocol
"On Microsoft Windows, MTP is supported in Microsoft Windows XP
if Windows Media Player 10 or later versions are installed."
I don't know exactly how you'd go about detecting whether
the camera uses MTP. Maybe it uses a class code in the config
information ? I would check the documentation for the camera,
as an easier way to find out whether that is what it is using.
It could be, that using a recent version of WMP will help you.
MTP is also used to enforce DRM, but in this case, that isn't
why they'd be using it (since the camera produces all its own
content which is DRM free).
