Hello again, Any word on the status of V4LCameras?
I installed Fedora on my Eee in hopes that it would have different kernel modules or something, no luck there either. Should I downgrade kernels to 6.24 to avoid v4l2? Any help would be greatly appreciated. Brad On Wed, Oct 22, 2008 at 2:59 PM, Bradford Barr <[EMAIL PROTECTED]>wrote: > Sadly, no dice using the other init.
