[linux-uvc-devel] Acer Usb Camera 5986:055a recogniced but no /dev/video0 entry

[arno wilhelm]

Hello,

I am trying to set up a new Lenovo Thinkpad L450 and everything seems
to work fine, except the build-in usb camera.
When loading the the uvcvideo module with "modprobe -v uvcvideo" I get
following message:

[ 1547.423473] media: Linux media interface: v0.10
[ 1547.427844] Linux video capture interface: v2.00
[ 1547.432887] uvcvideo: Found UVC 1.00 device Integrated Camera (5986:055a)
[ 1547.432994] uvcvideo: No valid video chain found.
[ 1547.433061] usbcore: registered new interface driver uvcvideo
[ 1547.433063] USB Video Class driver (1.1.1)


The driver seems to find the integrated camera but gives the error
message "No valid video chain found.". After that everything seems to
be ok again except that there is no /dev/video0 entry made in the
filesystem.

I know that this camera is not listed in the list of supported devices
(http://www.ideasonboard.org/uvc/#devices), but nevertheless I wonder
if somebody here can tell me if there is a chance that this camera
will be supported in near future or if there is a way I possibly can
help myself ?

Thanks and regards,
Arno


P.S.: I attached the output of dmesg, uname and lsusb to this email.
