[sane-devel] Brother MFC-L2750DW sane backend ?

[Richard Stein]

I seek information that I can apply to identify my brother 
printer/scanner. When I use lsusb on UBUNTU 18.04.1, I obtain this 
output. Where's the scanner device? It is connected to a WiFi interface. 
I require the productID, I think.

root at rmsbox:/lib/udev/hwdb.d# lsusb

I added this text to /lib/udev/rules.d/60-libsane1.rules:
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
LABEL="libsane_rules_end"

However, the device is not recognized. Kindly advise. Thx.
