The problem is that the "hp-config_usb_printer" command is taking too
long, and udevd kills the worker handling the device insertion, so it
never gets to the part of the udev rules that allow access by the
scanner group or, for that matter, the active console user. See
<https://bugs.launchpad.net/hplip/+bug/1185866> for more details.
A fix given there is to modify "/lib/udev/rules.d/56-hpmud.rules" to
change
/usr/bin/hp-config_usb_printer $env{BUSNUM}:$env{DEVNUM} ; fi
to
/usr/bin/hp-config_usb_printer $env{BUSNUM}:$env{DEVNUM} >/dev/null 2>&1
</dev/null & fi
Patch from Gentoo attached.
