xsane doesn't work

[Angelo Moreschini]

recently xsane stopped to work on my computer...

I don't remember exactly what i did when this happened (perhaps I made
something of wrong on the panel configuration setting ??).

They are several days that I manage to fix this problem.Actually I get the
error :
"xsane error during device I/O failed to open device hpaio:/usb/Deskjet..."

I get this error message after I modified the file /etc/sane.d/hp.conf
with the purpose to add inside it the exact manufacture name of my scanner
(Hewlett-Packard ID 03f0:ac11 ) .

Before I made this, I got other kind of error messages ,  as
"failed to obtain value of option source"
and
"failed to start scanner : invalid argument"

I know this is a common problem , I followed this link to try to work
around :
https://cromwell-intl.com/open-source/xsane-invalid-argument.html.  till
now without success.

here some lines of error that I got from juornalctl

You don't mention what model of HP printer/scanner you have?  DeskJet 2510? 
And did you previously install it using the hp-setup utility?

I have had several HP printer/scanners.  Currently have an OfficeJet Pro 8710.  I
think my previous one was a 6500.  I had both of them set as wireless and not USB and
haven't had a problem with either printing or scanning.

If you did use the hp-setup utility, maybe you should consider deleting the devices
and doing the setup again?

If you think you may have set something in error on the printer maybe you can reset
to defaults?

thank you Ed,

$ sane-find-scanner I get :
found USB scanner (vendor=0x03f0 [HP], product=0xac11 [*Deskjet 2510 series*])
at libusb:003:006

yes, on my computer it is installed hplip - and I  also tried to run
hp-plugin..
I don't remember if I needed hp-setup for the first installation.

I also tried to reinstall xsane but this wasn't enough (the file of setup
remained) .

xsane worked good for much time as till I made samting wrong ... (in the
setup panel (?))

According to
https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices... your
printer doesn't need a plugin.

I was actually suggesting deleting the printer devices and redoing hp-setup.  I found
that using the hp-setup and hp-toolbox utilities to helpful in getting
HP printers setup.

The message seems to be saying that http protocol is used over the USB port to
communicate with printer/scanner.  I'm not familiar with USB printer/scanners.  I do
wonder if you can print or if that fails as well?

And, how about resetting the device to the factory settings if you think you may have
made some changes by accident?

I tried to reinstall the printer, and made many other tries (also restoring
the default options from the setting table) without success.
But likely I have another computer that use the same printer... (it works
good with scanner mode).
So I copied the files in the directory ~/.sane/xsane from the other
computer in the computer that it doesn't worked  ....
*AND THAT RESOLVED THE PROBLEM.*

*Very strange the same working around didn't work by restoring the data
with the option "Load Device Setting"  in the tab "Preferences"*
Thank you Ed for your interest  to my problem.

Glad it all worked out.

FWIW, I would have done a "mv ~/.sane/xsane someplace" and then copied the stuff
from
another computer.  That way I could do "diffs" on the files to see what
changed.
