Hi,
I saw that this problem was already discussed lastmonth, unfortunately the
proposed solutions do not work for my case.
I have two identical laptops (two thinkpads X40) a Logitech QuickCam Notebook
Pro USB webcam and a Philips PCVC750K (ToUCam Pro Scan).
Both worked quite well on both machines which had an identical configuration:
up-to-date Fedora Core 4 for which I compiled and reinstalled pwc-10.0.11.
Now I made a fresh installation on one of the two laptops of the Fedora Core 5.
I saw that the webcams (in ekiga and in camstream) did not work (the carry on
working on the unmodified laptop). Nor did with a custom kernel 2.6.17-rc3
(latest available). Well, I tried to do as for the FC4. I tried both
pwc-10.0.12-rc1 and pwc-10.0.11, I tried them both on the 2.6.16-1.2096_FC5
standard fedora kernel and on my custom 2.6.17-rc3. In all the cases, with both
webcams the result is the same: with V4L1 (ekiga, camstream) a grey screen (even
though there are no apparent errors in the logs apart from
Apr 29 19:16:51 mirto kernel: pwc Failed to set LED on/off time.
), while wit V4L2 (ekiga) a generic error in opening /dev/video0 (also under
root, so it should no be a permission problem).
Suggestions?
Below, here you are relevant logs (2.6.17-rc3 with
