Fresh install of diamondback and Lucid in VirtualBox on my mac, I installed usb_cam (bosch-drivers), but get the following error when running:

VIDIOC_STREAMON error 28, No space left on device

I get a similar error when I try to run guvcview.

Any advice on resolving this issue? Is it a virtual machine problem?

How much space is on your virtual machine. Try running 'df -h' in your console, and posting the results.

What else is attached and running on your USB bus? This error typically means you have exceeded the bus capacity (for instance I frequently had this issue when attempting to access two high resolution webcam images when playing with stereo vision).

I had the same problem and solved it as follow:

sudo rmmod uvcvideo
sudo modprobe uvcvideo quirks=128

After doing that, I can acquire images from 2 cameras at the same time. Credits: http://renoirsrants.blogspot.com/2011/07/multiple-webcams-on-zoneminder.html. Checkout this link to see how to add this to your module conf so that changes become permanent.

However, using OpenCV to acquire images from the webcam still does not work. But using the usb_cam pkg, everything is fine.
