I have used POINT GREY FIREFLY MV FMVU-13S2C digital camera to work on Ubuntu 10.04 and ros electric(I am gonna call it VM1) and it worked very well. But when I install another virtual machine (Ubuntu 10.4 and ros electric also)(I am gonna call it VM2), the camera cannot be found.

I remember the steps that I got the camera worked in VM1 are:

  1. install camera drivers by "sudo apt-get install ros-electric-camera-drivers"
  2. Create an udev rule for usb adapter to recognize Grey Firefly MV USB camera by "sudo gedit /etc/udev/rules.d/40-pgr.rules" and add the following text into it.

ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2000", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2001", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2002", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2003", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2004", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="2005", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3000", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3001", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3002", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3003", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3004", MODE="0664", GROUP="pgrimaging"
ATTRS{idVendor}=="1e10", ATTRS{idProduct}=="3005", MODE="0664", GROUP="pgrimaging"
KERNEL=="raw1394", MODE="0664", GROUP="pgrimaging"
KERNEL=="video1394*", MODE="0664", GROUP="pgrimaging"
SUBSYSTEM=="firewire", GROUP="pgrimaging"

  1. then I follow

Install the modules

modprobe ohci1394
modprobe video1394
modprobe ieee1394
modprobe raw1394

Create proper 1394 devices

cd /dev
mknod raw1394 c 171 0
chmod 666 /dev/raw1394
mkdir video1394
cd video1394
mknod 0 c 171 16
mknod 1 c 171 17
chmod 666 /dev/video1394/*

Set user paths

su user

Check for the LD_LIBRARY_PATH. It should contain /usr/local/lib. This is necessary to run the applications with the help of the shared object file.

I applied exactly same steps to VM2. however, when I run "rosrun camera1394 camera1394_node", camera cannot be found.

Following are some outputs of VM1 and VM2 for your information.

terminal: lsusb -t

Are you running both VM's at the same time on the same real machine? It is probably not possible for both to connect to a single USB device. Even back-to-back tests might encounter problems with device allocation between the virtual machines.

I restart the computer and only open one VM, but it still doesn't work. I noticed that raw1394, ohci1394, video1394, ieee1394 have been removed once I restart the computer. Is there a way to permanently install these modules?

They should get loaded automatically when a 1394 device is detected. The modprobe command can load them manually. You can put those commands in /etc/rc.local, but it should not be necessary.

But in VM2, the modules are not automatically loaded when I plug in the camera. And in VM1, even I didn't plug in the camera, the modules are still there and they won't be removed after restart the VM.

And I list the devices of VM1 and VM2. I found VM1 has devices raw1394, v4l and video0 which VM2 doesn't have. I guess video0 is my webcam, I don't know why I even cannot recognize webcam.

Ok, I just forgot to connect my webcam to VM2. So it's only raw1394 that VM2 doens't have but VM1 does have.

I suspect that it is the "host adapter" that gets allocated to VM1 and triggers those loads. I don't believe that hardware interface can be shared between multiple VM's.

I reinstalled the ubuntu on real machine (not virtual). But the problem still exists, there is no raw1394 after I plug in the firewire camera.

Better consolidate resource and avoid duplicate (for better maintenance). I've replaced all the text with just a link to your answer in another thread.
