That is a possible upstream  bug in SANE for this device.

Hello alain,

thank you for spending your time helping to make Debian better with
this bug report.

In the past, the error message "error: SANE: Error during device I/O
(code=9)" always meant an error in the hplip package. In addition, the
version hplip 3.21.2+dfsg1-1 is also heavily buggy.

I therefore assign the error to the hplip package.

Jörg

What did you change before the scanner stopped working?  I see that
you are running hplip 3.21.2 which is not yet in testing.  Does a
downgrade to 3.20.11+dfsg0-2 fix the issue?  This would be very
important to know.

Some HP devices may need a proprietary firmware plugin that Debian
cannot ship.  What have you installed for firmware?

It would also help if you could provide the following:

* output of "scanimage -d hpaio:/usb/ENVY_5530_series?serial=CN595530XD06BX -vvvv --dont-scan > /tmp/si.ds"
  (scanimage is from package sane-utils)

* output of "scanimage -d hpaio:/usb/ENVY_5530_series?serial=CN595530XD06BX -vvvv --test > /tmp/si.test"

* the relevant dmesg output

* a tshark (package tshark) trace of the USB traffic when trying to
  scan (tracing USB traffic is a bit of an advanced topic; searching
  for "wireshark" "usbmon" on the web will give you some tutorials,
  but [1] and [2] should already be good starting points).

If you can make the scanner work with a downgrade, try to do the same
with the working configuration and see what is different in the
failing one.  Use diff for that if possible.

What concerns me is that lsusb throws errors which indicates that this
might be a problem with the device itself.

Good luck!

Hello Jörg,

There isn't any bug in hplip. Please see #983349:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=983349

I would have closed the report but it has information relating to a
failure of libsane-escl. Therefore, I reassigned the bug to libsane1
for the attention of its maintainer.

Regards,

Brian.

Hello,

please can you check if the bug in

 - sane-backends 1.0.32-4 (currently in testing)

still exists?

Thanks in advance
