After I upgraded to the new kernel I can no longer import images from my PTP-camera connected with usb and not scan images with my usb scanner. It worked before the upgrade. It is some permission problem because it does work when I try to do it as root. So I guess the new kernel changed some interface that HAL or UDEV uses. I don't know whos fault it is, maybe one of these should adapt to the new kernel or maybe the kernel shouldn't have made it break in the first place.
