Juan, I'm also using karmic, and all my uvc cameras work just fine with the latest kernel (2.6.31-10)
Could this be related to your usb hub ? Have you tried booting with the camera disconnected and plugging it after booting (hot plug) Do you see similar the errors in this case? Karmic upstart/initscripts have been causing some problems, I had the boot process broken at least two times now. Udev also has had is share of problems, the latest updates have fixed most of these issues, but please remember that karmic is still under heavy development and is far from stable.
