I am trying to set up a virtual machine which will act as a home security system. (If you've chatted with me in The Tavern, you may know why...) I purchased two USB webcams (Microsoft LifeCam HD-5000) and am trying to get them to work with Motion. However when I connected them to my Ubuntu 10.10 VM, no /dev/video devices were created. dmesg said:

jnet@sharon:~$ dmesg|tail
[  558.421978] uvcvideo: Failed to initialize the device (-5).
[  558.423487] usbcore: registered new interface driver uvcvideo

[  569.042808] usbcore: deregistering interface driver uvcvideo
[  570.840343] uvcvideo: Found UVC 1.00 device Microsoft® LifeCam HD-5000 (045e:076d)

[  595.775370] uvcvideo: Failed to query (129) UVC probe control : -110 (exp. 26).

[  595.777012] usbcore: registered new interface driver uvcvideo
[  595.777018] USB Video Class driver (v0.1.0)

There's a lot of results on Google for "uvcvideo: Failed to query (129) UVC probe control : -110 (exp. 26).". many people were saying to unload the uvcvideo module and reload it, because it loads before the usbaudio module. But no amount of unloading and reloading worked. A custom compile of the uvcvideo.ko module was suggested but the link to the source was dead.

Is there any way to make these webcams work under a *nix-like system? Please note it does not have to be Ubuntu, I was setting up a brand new VM for this purpose so I am open to any unix-like OS, be it Fedora, CentOS, a BSD flavor or even Open Solaris or similar.

Here are two links, one is from Mint-linux saying it works in Mint. There are two videos on Youtube showing it being used with Mint and Ubuntu.

Awesome, I'll try Mint this weekend and see if that works! – Josh Dec 15 '10 at 14:13

Turns out the issue was VMware. No matter how hard I tried I couldn't make the camera work inside a virtual machine under VMware Server 2.0. Linux Mint was the only distro which even recognized it, and even then I kept getting errors that the camera could not be opened / IO errors.

Installing uvcvideo, cheese and motion directly on the host worked fine.

Three years later on a new host running VMware ESXi 5 I didn't have any of these problems, so it was a VMware Server 2 issue. (Now very, very outdated)

Have you tried running virtualbox as root, then dropping the camera in the virtual machine? – Adam F Feb 17 '14 at 21:31
No @Adam, and I have since migrated to VMware ESXi which resolved the problem. I'll update my answer. – Josh Feb 18 '14 at 14:45
