udev_resource thinks that KVMs are CAPTURE devices, which causes camera tests to run on desktops with no camera

[Brendan Donegan]

I noticed that the camera/multiple-resolution-images test was being run on some desktops and when I went to check it out, it seems that the IBM KVM connected to these desktops is being categorised as a CAPTURE device by udev_resource. This may be strictly speaking correct, but it causes undesired behaviour such as camera tests running on systems with no camera. Devices which are actual cameras should either have a seperate category or KVMs should not be listed as CAPTURE devices.

Could you get output of "udevadm info --export-db" so we can see why udev_resource thinks the KVM is a capture device?

Thanks!

You can search for 'Avocent' to find the KVM device

KVM Identification is performed by looking at the KEY bitfield to check if BTN_MOUSE is present.
In such case a camera with a mouse button is considered as a KVM hardware device.
