Hi,
I tried to get a Logitech QC Pro 5000 working on my
SuSE 10.0 box with kernel 2.6.13-15.16-default using
the UVC driver.
But the video screen of any application I tried just
remains black.
Below I've attached some info on what I did.
Any help would be most appreciated.
Thanks
Wolfram
1)
===============================================================
I did:
$ svn checkout
svn://svn.berlios.de/linux-uvc/linux-uvc/trunk
$ make -C /home/thisuser/MyKernel/ M=$(pwd) modules
$ su -c 'make -C /home/thisuser/MyKernel/ M=$(pwd)
modules_install'
$ su -c 'depmod -ae'
There where no apparent errors during compile and
install.
Ater install I have one new module, i.e. 'uvcvideo.ko'
in /lib/modules/2.6.13-15.16-default/extra
Pluging in the cam I get:
$ lsusb
Bus 004 Device 003: ID 046d:08ce Logitech, Inc.
$ lsmod | grep uvc
uvcvideo 46724 0

usbcore 112512 7
snd_usb_audio,snd_usb_lib,uvcvideo,usb_storage,uhci_hcd,ehci_hcd
$ tail -f /var/log/messages

All this looked fine to me but then I tried:

===============================================================
GnomeMeeting. It does not work: black screen

Your video driver doesn't support the requested video
format.
3)
===============================================================
xawtv. It does not work: black screen

with
$ tail -f /var/log/messages

if I play arround with the xawtv controls I get lots
of messages from
xawtv of the type:

in the latter case I also see messages in
/var/log/message of the type

Hope all the preceeding helps.
