Same issue in Karmic : all worked fine in Jaunty, but I was unable to install Brother Scanner DCP-7030 on a fresh Karmic Koala (printing and driver are OK).

I donwloaded sane-utils / Brscan3 :
Scanner Driver USB scan-key-tool :

I did : sudo gedit /lib/udev/rules.d/50-udev-default.rules
in section "libusb device nodes", I replaced 0664 by 0666

But no scanner was identified by xsane.

I used "sudo lsusb" command to see my scanner, it was on Bus 004 Device 003: Brother Industries, Ltd DCP-130C

Reason of impossible use was that device 3 was root owned.

So I opened Nautilus as root, went to dev/bus/usb/004 and device 3 (003 file) was with root permission only.
I modified it for my user name and now xsane works well, scanner is recognized.
