I never looked before I loaded uvcvideo. If I unload it, it doesn't happen afterwards, but then again I'm not doing anything else with any USB devices. I suspect it has something to do with the 64 bit build of Fedora 10 ... It works almost perfectly if I install the 32 bit version of Fedora 10 on the HD! I can modprobe and rmmod the driver tens of times with now errors and then when I reload it the last time it works just like it did after I first booted. Should presume that other folks have run uvcvideo on a 64 bit version of another distribution? I can only imagine that the 64 bit kernel build in Fedora doesn't work well with my laptop (HP dv5 with AMD) So now I have a different problem with the 32 bit Fedora 10. Ekiga 3.0.1 (which is the secondary purpose of this laptop) is stuck in a very low resolution namely 160x120. Now what is odd is that this resolution isn't even available in ekiga. I set it with cheese and now I can't change it with either of the two. If I change it in ekiga, it stays the same size (160x120) but with a black border around it to fill in the rest of the new size. If I change the resolution in cheese to anything other that 160x120 I get a completely black image. In guvcview I can set any resolution I want from 160x120 to 640x480 and they all work as they are suppose to but changing it in guvcview has no effect on ekiga or cheese. This still happens after a cold boot and with a different user. If I boot from the live CD it works at any resolution I set it to. Is there some file shared between cheese and ekiga that stores the webcam resolution?
