The trick with USB (or indeed any device) is to work out whether
there's a supported driver for it, either in the kernel or as a third
party one.
Since you've said that a USB memory stick works okay, then it's fairly
safe to assume that the correct chipset drivers are being loaded by
Ubuntu for your netbook - therefore it's a case of finding a driver
for the Olympus DVR.
One of the quickest ways to start finding out is to get the device USB
vendor and device ID from the system using the "lsusb" command.
Run it from the command line without the DVR plugged in, then plug in
the DVR and run it again, noting any differences. Hopefully there's
just one additional line that will point to the ID of the DVR.
Here's a sample output of lsusb from one of my PCs, I use Gentoo
Linux, not Ubuntu, but hopefully you should see something fairly similar:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 005: ID 14cd:8168 Super Top
Bus 002 Device 006: ID 041e:403a Creative Technology, Ltd Webcam NX Pro 2
Bus 002 Device 005: ID 045e:00dd Microsoft Corp. Comfort Curve
Keyboard 2000 V1.0
Bus 002 Device 007: ID 045e:00d1 Microsoft Corp. Optical Mouse with
Tilt Wheel
The important numbers are the two sets of 4 hex digits after ID that
are separated by a colon which are the vendor and device IDs. e.g.
045e:00dd for my Microsoft Curve Keyboard.
The trick now is to just to a Google Search with "Linux kernel driver
045e 00dd" and just see what info you can get from there.
I use Ubuntu very little so don't know what they do with the kernel
but I suspect that most drivers in their kernel are built as modules
so that the appropriate ones are loaded for the detected hardware -
but it could well be that due to conflicts or support only through
"Staging Drivers" that some modules might not be available without
recompiling the kernel, or maybe you just need a later kernel.
But once you establish whether or not the DVR is supported, then that
should lead you on to what needs to be done next.
If you do want to send me the device IDs for the DVR then I will see
what I can find out - also let me know what kernel version you are
running from "uname -a" on the command line.

What does dmesg give you when the device is plugged/unplugged?
It's unusual
that an audio device doesn't just appear as mass storage.

Hello Tim
Thank you for your response.
The computer identifies the device (sudo lsusb) but I still can't see
the actual files on it.
Output of dmesg with device plugged in then removed is attached as a
screen dump.
I don't understand: ohci_hcd
Important line from dmesg...
[timestamp] usb 2-5: new full-speed USB device number 4 using ohci_hcd
Tony,
The line above tells us that ohci_hcd recognises the device as a legitimate
USB device, which is good news. "ohci_hcd" is part of the USB stack. Someone
else may be able to provide more info on exactly how it works.
After a bit of searching I found this thread:
http://ubuntuforums.org/showthread.php?t=1012335
About 60% down the page it mentions the ODVR project which should be a good
place to look for advice.
The following link might also be helpful:
http://htyp.org/Olympus_VN-480PC
Good Luck,
Tim B.

Success !
I've been playing around with it since lunch finished - i.e. for a while!
The program 'odvr' kept reporting that my test files were an unhandled
quality (the VN-2100PC records in XHQ, HQ, SP or LP).
After some experimentation I found 'odvr' works only in XHQ - not truly
a problem as I never get near the limits of the device storage.
So here we have a very happy bunny now able to do EVERYTHING he needs
using Ubuntu 12.04 Linux.
Thank you all - especially Tim - for exemplary support.
Ain't Linux great!
