The scanner in my USB-connected Brother DCP7030 multi-function device stopped working when I upgraded my Lubuntu to 22.04. In an attempt to get it working, I upgraded further to 24.04, but it still refuses to play ball. The printer in the MFD still works fine. I've installed the Brother drivers and fix to run as admin mode from the brother website. https://support.brother.com/g/b/downloadlist.aspx?c=gb&lang=en&prod=dcp7030_all&os=128 but it still refuses to be visible to SANE.

Your USB scanner was (probably) detected. It may or may not be supported
by SANE. Try scanimage -L and read the backend's manpage.
$ scanimage -L
No scanners were identified.
If you were expecting something different, check that the scanner is plugged in,
turned on and detected by the sane-find-scanner tool
