Webcam troubles in VM

**apple_man** · February 13th, 2016

Hello community,

First of, I hope that this is in the proper section.

Alright guys, this is driving me insane! My webcam in Virtual Box won't work.

I am running Ubuntu 14.04.3 LTS in Virtual Box 5.0.6, on a Windows 10 host. I need a webcam for a computer vision project in OpenCV.

I specifically bought the Trust SpotLight Webcam Pro since it was supposed to work as per this list. When I run the video.py test I just get a black screen.

When I run lsusb it gives me this (seems like the webcam is recognised):

Code:

Bus 001 Device 002: ID 0c45:6340 Microdia 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 80ee:0021 VirtualBox USB Tablet
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Cheese also gives me a black screen, and returns this in the terminal:

Code:

libGL error: pci id for fd 10: 80ee:beef, driver (null)
libGL error: core dri or dri2 extension not found
libGL error: failed to load driver: vboxvideo

I added the USB device filter in the VirtualBox settings (3D acceleration is off), however when I hover over the filter I see that the state is not supported.

Can this be fixed, or should I return my webcam and get a new one? If so, how would I know which one will work since the list obviously contains errors.

Thank you.

EDIT: Tested with Logitech C270 an C310, same result........

EDIT 2: Solved it by using the integrated web cam
I don't know if this has anything to do with it, but this is how I solved it. In Virtual Box I went to the USB filter of the webcam, and removed everything except the VendorID and ProductID (I found that here). But then when I clicked OK, Virtual Box didn't respond, so I had to reboot my PC. When I opened up the VM, my integrated web cam appeared under the Devices menu. I still get the same errors, but it works! I think those errors have something to do with 3D acceleration?

So is it recognized in Ubuntu 14.04? (the host). The doc's you posted has it's ID as 0c45:62c0... I do not see that specific address in your output. Are you saying it is showing up as 0c45:6240? That is showing uought that with Macrodia, someone cam up with a drier, but you had to compile and add yourself manually...

Found info on that here

Oh man, you are right, I totally missed that! It does not show up as 0c45:6240, it shows up as 0c45:6340.

But that is so odd since I do have the samel model, but it has another ID. Hmmm...

The link you gave does not work? (error establishing a database connection)
