Linux – How to get the reason for wakeup

The logs there are telling you that you're missing a bunch of dependencies. You can go the slow route of installing each one individually or separated by a space. However, I'm running ubuntu 11.04 (latest stable version) and have not experienced the same issues. Only difference could be that I did (below) after a new install.

sudo apt-get update && sudo apt-get upgrade && sudo apt-get install build-essential

When I go to install vlc

sudo apt-get install vlc

It tells me that I need to install dependencies. I type Y to install them. The process goes through normally and installs.

I don't have your environment and cannot test, but this excerpt from the gphoto FAQ seems to say that this might be a matter of permissions, rather than some program monopolizing the interface.

The following quote contains a link to the Setting up permissions for USB ports chapter that you could check.

Why do I get the error message "Could not claim the USB device"?

You have to make sure that no such kernel module is loaded and that you have set up the permissions on your USB device correctly, such that you have (non-root) write access to the camera device. How to set this up, is described at Section 4.3, Setting up permissions for USB ports.

This can also happen with cameras that works as USB Mass Storage devices. A notable example is if you have an Olympus Camera that gets auto-detected as an Olympus C-2040Z. In this case, you can try, if you run Linux, to remove the usb-storage kernel module and attempt to use libgphoto2 with it. But, unless you want to control the camera (not all the model supports it), it is not a recommended solution. Keeps using USB Mass Storage. Some of these Olympus supports to be switched to "PC Control" mode in order to be remote controlled with an external program like one using libgphoto2.
