Package: udev
Version: 241-5
Severity: normal

Dear Maintainer,

Under Debian 10 rc1, when I plug in my USB camera (the very common logitech
c930e), 2 devices are added (e.g. /dev/video0 and /dev/video1).

v4l-info works on /dev/video0, but fails on /dev/video1
(VIDIOC_G_FMT(VIDEO_CAPTURE): Invalid argument). When I try to access the
device using gstreamer it tells me that /dev/video1 is not a capture device.

In stretch I don't see this behavior.

Attached are syslog, dmesg, v4l-info for both devices, udevadm for both
devices, lsusb, lspci.

Let me know if any other logs can be of help.
