Did you include CONFIG_USB_PRINTER support in your new kernel?  If it's a module,
is the module loaded?

There are some usb printer drivers (eg my HP printer) that don't want the usb
useflag set in the cups package, but I don't know about Brother printers.  You
might build cups both ways as a test if you can't find anything else wrong.
