xsane fail "invalid arguments" // sane replaces correct driver "genesys" with "Device" and fails

English Hardware
1

I am using Open SuSE 15.0 (formerly upgraded from leap and now refreshed).
The last steps:

  • xsane worked after dist-upgrade to latest code about a year ago
  • minor updates for mozilla, teamviewer, and some other apps
  • xsane did not work anymore
  • asked for “zypper update”, got again new libs and rpms for mozilla, vdrift and some more
  • xsane still does not work
  • using “yast scanner” (did not really work well, deleting an inactive configured scanner, that came back later)
  • checked /etc/sane.d
  • usb ids match the configured scanner
  • (dll.conf.rpmnew swapped with dll.conf), no change in content (some more comments now)
  • sane.conf unchanged
  • starting still leads to error “invalid argument”
  • reinstalling xsane
  • checking that all libusb are installed (was true)
  • found only a few executables of xsane and not config files outside /etc/sane.d
  • Now following the trouble-shooting section of https://en.opensuse.org/SDB:Configuring_Scanners
    it turns out that the (correct) configuration gets lost between sane_init() and sane_open():

me:~# sane-find-scanner

sane-find-scanner will now attempt to detect your scanner. If the

result is different from what you expected, first make sure your

scanner is powered up and properly connected to your computer.

No SCSI scanners found. If you expected something different, make sure that

you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan], chip=GL842) at libusb:001:028
could not fetch string descriptor: Pipe error
could not fetch string descriptor: Pipe error

Your USB scanner was (probably) detected. It may or may not be supported by

SANE. Try scanimage -L and read the backend’s manpage.

Not checking for parallel port scanners.

Most Scanners connected to the parallel port or other proprietary ports

can’t be detected by this program.

OK, i.e. using “scanimage” kicks the scanner from the USB bus. Why?

I added *** where the backend was determined correctly,
but in the next line ‘sane_open()’ uses “Device” instead of “genesys”
The other debugging options did not change the above output.

It looks to me like a binary in error. How do I resolve this situation?

2

Bug report territory IMHO.

Hi
Unlikely as the version in use is EOL :wink:

@OP, can you upgrade to Leap 15.1?

4

Yes it is a good idea to upgrade to see if the regression is still evident (and report if necessary) :wink:

Thanks ! I am going for bug resolution.
It is also triggered by this not very specific “askubuntu” comments:
https://askubuntu.com/questions/724366/xsane-fails-to-open-device-invalid-argument

However, it is interesting that the system behaves now differently.
There was no reboot, but the system was left running since yesterday.
The (by yast) deleted entry “hpaio” reappeared in the device list (driver is still removed from dll.conf)
Now the device is recognized but kicked out again when trying to open it.
The rediscovery during the xsane startup assigns the next usb address.

Hi
How do you expect resolution from an unsupported, end of life release, a bug report if created will be closed as won’t fix, there are no more updates etc?
