Failed to open Olympus device: couldn't claim interface

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Plug in VN-480PC
2. Type any command to access the device e.g. odvr -e or odvr -l

What is the expected output? What do you see instead?

List of files / download / whatever. Instead, I get "Failed to open Olympus
device: couldn't claim interface"

What version of the product are you using? On what operating system?

odvr0.1.4.1x64 on ubuntu 8.04x64

Please provide any additional information below.

It does recognize that a device is plugged in, because when I run odvr
without the device plugged in, I get "couldn't locate device."

Ack. Sorry, running as sudo fixes this problem. Might I suggest to add that 
fact to
the help file? Thanks for this great piece of code!

Sudo shouldn't be required if the package was installed correctly and you're a 
user
of the audio group. It's possible that Ubuntu 8.04 has diverged enough that the
packages don't work correctly (they're built on Ubuntu 7.10). That said, it's 
well
known our packages need some TLC as well as some nice documentation on the 
wiki. I'll
try to make these priorities for the next release.

I upgraded to Ubuntu 8.04 and had the same problem.
I resolved it by changing the 41-odvr.rules to

SUBSYSTEM=="usb", ATTR{idVendor}=="07b4", ATTR{idProduct}=="020d", 
ACTION=="add",
GROUP="audio", MODE="0664"

I don't know anything about udev.  I looked at other udev entries and 
experimented a
bit so I have no idea if this is the correct solution.  All I can say is that it
worked for me.

Thanks to #3! It really works with Ubuntu systems.

Thanks for the work on this - I am now able to use my voice recorder. Am using 
the
alterations to udev suggested in #3.  Thanks again.  Nick

The fix from #3 also works for me with Ubuntu 8.10 x86-64.
