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.

I'm closing this bug report.
That you have two video* devices is not necessarily a bug, btw.
