I insist: it is not possible with SANE to specify a list of extra
scanners.
And since SANE lies between applications and back-ends, it is the
correct place to implement it.

Hi.
This may be an obvious thing, but I cannot find the answer.
I can scan with:
scanimage -d "hpaio:/net/deskjet_3050a_j611_series?ip=10.0.1.155"
xsane "hpaio:/net/deskjet_3050a_j611_series?ip=10.0.1.155"
