FIXED -- Skanlite "Operation not supported", similar with xsane

[dibl]

OK, my problem is fixed -- somehow ....

don@dibl-patience:~$ scanimage --list-devices
device `epson2:libusb:003:003' is a Epson Perfection1640 flatbed scanner
device `epkowa:usb:003:003' is a Epson Perfection 1640 flatbed scanner
The second device shown above, the "epkowa" scanner, works, if I select it from the (new) two-scanner list found by skanlite. There was no such scanner found before I installed this driver, but the "epson" scanner always worked. Now the "epson" scanner still does not work, but I have my scanning capability back, so I'm marking this issue resolved.  Thank you very much, charleyheinz!

Hmm,
ich hänge mich mal hier mit dran.
Mein Brother MFC-5890CN wird aktuell auch nicht mehr übers Netz erkannt.
Vor etwa 2 Wochen gings noch.
USB probiere ich gleich noch.
Drucken geht, aktuelle Treiber vom Brother habe ich auch installiert.
Mit sane-find-scanner wird er auch nicht entdeckt.
Die Brother Konfiguration in /usr/local/Brother scheint auch ok (IP-Adresse).

Schleppe jetzt den MFC rüber und probiere es mal mit USB.

Hmm,
can it be that the file /usr/lib/udev/rules.d/60-libsane.rules is obsolete or missing?
I can find only 60-libsane1.rules dated 18.Aug. there
Thes scanner is now found via USB with sane-find-scanner but neither recognized with scanimage -K or xsane

regards

Kann es sein das die Datei /usr/lib/udev/rules.d/60-libsane.rules obsolet ist oder fehlt?
Finde nur die 60-libsane1.rules mit Datum 18.Aug.
Scanner wird über USB mit sane-find-scanner zwar erkannt aber weder mit scanimage -L
oder xsane wird er gefunden.

Hmmmmmm.  No 60-libsane.rules, but instead 60-libsane1.rules

So, checking list of supported devices at /lib/udev/hwdb.d/20-sane.hwdb. And there I find (neither in alphabetical nor numerical order ) the following:

Code: [Select]

# Epson Perfection 1640 | Epson GT-8700 | Epson GT-8700F
# Epson Perfection 1640SU | Epson Perfection 1640SU PHOTO
usb:v04B8p010A*
 libsane_matched=yes
 So, that's my scanner. Still confused about this one.

Do you suppose if we rename 60-libsane1.rules back to 60-libsane.rules, that it might fix the problem?

[ReinerS]

@dibl:
Unfortunately renaming libsane1.rules back doesn't help.
But I will have a closely look at 20-sane.hwdb.
Maybe the problem can be solved within there.

Ist jetzt zwar ein Tip für Bullseye, aber probier doch mal:

Code: [Select]

apt install avahi-daemon

[dibl]

Hi rolo48

avahi-daemon is installed here. The "epkowa" scanner still works, and the "epson2" is still broken.
