VirtualBox USB. Sometimes things can be simple.

First of all if you find this post because you want USB to get going on Linux, than you need to know that if you use the open source varian VirtualBox USB – that does not support USB on purpose. Only the closed source version lists USB as a feature. So you have to fetch the version from www.virtualbox.org.

Secondly, there are still issues with USB on VBox in general. But there is a trivial solution for many devices if you use the latest Vbox version >3.1.2:

  • You need to enable the devices by adding a filter in the USB configuration menu. No device without a filter will work and all devices will be grayed out! (And the is a¬† nice HOWTO and also)

Previously I tried all the funny tricks that you can find on the net. Nothing helped – but nowhere I found this. So I decided to write it down. I did not kow what a USB filter was and assumed that rather than enablig it was meant for disabling USB devices. Lesson learned.

Yet I was not able to enable a Canon PIXMA in that way. Not sure what the cause is. I also still have issues with DVD/CDROM (which I solve by typing “eject” in terminal). But what is nice that a Windows XP on a 64bit Ubuntu 9.10 starts in about 6 seconds inside VirtualBox (unfortunately not my system).

New digital remote control

Inspired by the pseudo hologram of CNN I got a vision about new remote controls. It could work like this:

Imagine you have a full 3D virtual view of a house – or a room on a screen. Now you can move through the room and do something with the objects like switching on the light in a room when right clicking on either the virtual¬† switch or the room itself. so every room could have attributes that you can set like “set temperature” etc. The nice thing would be that you are able to set these things over internet.

Or you can use it to balance the speakers of your hi-fi system. Or to connect different objects like drag something from your computer in room A to the hi-fi system in a room B.

And maybe related to SecondLife it could be nice if you could invite people virtually to a virtual copy of your home, if they had a virtual character. They could move around your home and look around as they were there. Before that sure one would need a real 3D virtual copy of the rooms. An open question would be how one would deal with changes in rooms – and sure sometimes one would like to exclude people. OTOH the 3D data would also be cool to load virtual furniture. My guess is that todays 3D technology can is quite able to recognize these structures. It would be important to get the right images nto the computer. I would think that one starts with a few pictures – then the software tries to get where top and bottom is and what fits – and the user can help my declaring where the bottom is. Then the computer should ask to take more pictures from certain perspectives. So the virtual world would grow. Then it would also be nice to be able to cut out some furnitures to be able to push them around – or to test how you get them through a door.
