Comment 12 for bug 1747060

Hi again,

Thank you brian_p and Nishitha Antony for having a look into this.

The scanner is definitely working, as I can use a copy button to scan a document and print it out.
I can also use scanner to save image into the USB Thumb drive or into build into this printer HDD.
But I cannot use scanner to save files to my laptop or to scan documents from my computer.

'/etc/sane.d/dll.d/hplip' says that it is hpaio

As for the USB, here are the results, it's exactly like you said, one had a '+'.
crw-rw-r--+ 1 root lp 189, 276 lut 14 12:28 /dev/bus/usb/003/021
then:
getfacl /dev/bus/usb/003/021, says:
# file: dev/bus/usb/003/021
# owner: root
# group: lp
user::rw-
user:will:rw-
group::rw-
group:scanner:rw-
mask::rw-
other::r--

So, I'm there, user: 'will' and it's also read-write permission.

I did try the same on Windows 7 VM in VBox.
Device was properly recognized, I have installed scanner software/drivers from HP website, but it could not find any scanner (I did tick the proper USB device in devices tab).
Did some search, and found that, even though it used to work in earlier devices, HP has dropped such basic function like scanning from a PC, both by USB or network.
Some guys already complained about it:

There are some other options like shared folder on you laptop/PC to which a scanner should save your images, I'll have a look on it.
Other options are to send email with scanned image, but I don't like that option.

Topic can be closed with note, that this printer does not support scanning over USB nor network.
No such info is in the manual, at least I couldn't see it.

Thank you guys for your patience and knowledge.
Have a great evening,
Martin
