Sorry for today's noise on the list, your commits have fixed
networked scanning with MF8540 indeed: RELEASE_1_0_24-296-g0655b05
scans over ethernet just as fine as it does over USB now (so it
probably qualifies as "Perfect" for me given that I have no clue
about ADF use anyways but then again I'm not a demanding user).

As mentioned in another today's message, I scanned background!

The problems with two scanimage/xsane runs in a row are
still there as of today's git though.

Is ADF facility onboard or an option there?

Hm, usb cable seems to suffice indeed, that has led to another
round of iR1133 experiments (will come as yet another message).

That looks like "minimal" to me as it's apparently been tested
and can squeeze at least a scan per replug but oh well :-)
