[sane-devel] HP ScanJet Pro 2000 sudden failure

[Ellis Cohen]

Thanks for your help!   IPP-over-USB *was* the culprit (although I have no idea exactly what latest-update from Fedora changed previous behavior).

I determined that for my configuration, it was least-invasive to simply execute

> ipp_usb_was_active=false
> sudo systemctl --quiet is-active ipp-usb
> if [ $? -eq 0 ] ; then
>    ipp_usb_was_active=true
>    sudo systemctl stop ipp-usb
> fi

before scanning, and

> ${ipp_usb_was_active} && sudo systemctl start ipp-usb

afterwards.

Again, thanks muchly!
