Has anyone been able to get a dcp-7040 scanner working properly? On 14.04 I've gotten it to work by using the Brother install tool

1. adding 

```
# Brother scanners
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="01ea", ENV{libsane_matched}="yes"

```

to the end of `/lib/udev/rules.d/40-libsane.rules` and editing `/lib/udev/rules.d/50-udev-default.rules`
2. by putting 

```
# 'libusb' device nodes
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0666"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", IMPORT{builtin}="usb_id"

```

into that folder and now everything works.

I can't for the life of me get the scanner to work in 16.04 tho. I can print, just not scan. It doesn't even show the scanner as available in simple scan.
