I found the problem
It does not work because the PSC 1315 (it is actually a psc 1315) identifies
itself as
ATTRS{product}=="psc 1310 series " with a space before the end of the quote.
The space is incorporated as an underscore in the device uri for cups and for
sane backend hpaio. (My cups uri is as setup by hp-setup is:
hp:/usb/psc_1310_series_?serial=CN48IB72SYO2 (note the underscore after
series.
When hpaio looks at /usr/share/hplip/data/models/models.dat, it only finds
[psc_1310_series] (no trailing underscore). As a result, it has no usable
scanners. Adding an underscore to the model.dat file [psc_1310_series_]
enables scanning, but breaks recognition by hp-setup and hp-toolbox (and
probably everything else that works correctly). Under hplip-1.6.10,
everything worked correctly.
hpaio is using the model number to look in models.dat, when it should be using
the model number without the trailing underscore!
Please fix this.
Proof is as follows:
After installation with hp-setup and exporting SANE_DEBUG_HPAIO=8
SANE_DEBUG_DLL=12

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 (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
[dll] sane_exit: exiting
[dll] sane_exit: calling backend `hpaio's exit function
[hpaio] sane_hpaio_exit(): scan/sane/hpaio.c 1827

Since it seems that hpaio finds "no psc_1310_series_ attributes found in
models.dat" (note the underscore after series) in its second to last message
before exiting I looked at /usr/share/hplip/data/models/models.dat and found
[psc_1310_series]
I changed it to
[psc_1310_series_]
note the extra underscore at the end.
Now I run scanimage -L and everything works.

But if I run hp-setup it can't find the device until I delete the underscore
that I added. Which breaks scanning again.
I think the trailing underscore is coming from the PSC itself. When I run
# udevinfo -a -p `udevinfo -q path -n /dev/bus/usb/004/004`
looking at parent device '/devices/pci0000:00/0000:00:0b.1/usb4/4-1':
KERNELS=="4-1"
SUBSYSTEMS=="usb"
DRIVERS=="usb"
ATTRS{configuration}==""
ATTRS{serial}=="CN48IB72SYO2"
ATTRS{product}=="psc 1310 series "
And viola, that is where the trailing underscore comes from, note the space
before the closing double quote in ATTRS{product}, it is hard to see in some
fonts.
Here is part of the hp-check, but it bombs out with RuntimeError: maximum
recursion depth exceeded.
