epson scanner v500 - epkowa driver does not work any more on x64 system since 13.2

Created attachment 673265 [details] Scanner config and Error msg Configuration with yast2 give a warning that the driver may not work on 64 bits system. The scanner is recognized. Commands are accepted. Cannot make test successfully; the scanner scan but does not output anythings. Using iscan, I got a more precise error : Scanner have no write access. When searching a directory to save a scan, got a disk full warning. This scanner work correctly on windows 10. This scanner was working correctly 2 years ago on Opensuse 13.1.
The iscan software is proprietary third-party driver software. There is nothing what we (openSUSE) can do in case of issues with third-party software. Accordingly the issue is invalid for us (openSUSE). You can only contact those wherefrom you got the proprietary software for any kind of help and support, see "Third-Party Scanner Drivers" at https://en.opensuse.org/SDB:Configuring_Scanners FYI: Regarding using 32-bit scanner driver software: In general on 64-bit x86_64 systems you can also run traditional x86 32-bit software. To use a traditional 32-bit scanner driver software you must run the whole scanning software as 32-bit software. This means you have to use the 32-bit sane-backends RPM package. To avoid conflicts you probably have to remove your currently installed 64-bit sane-backends RPM package and instead install only the 32-bit sane-backends RPM package. When the scanning base software is 32-bit software it should probably work to use a 32-bit scanner driver software. Regarding "no write access": See "USB scanner access permissions via udev" at https://en.opensuse.org/SDB:Configuring_Scanners Regarding "disk full warning": In general no software works when your disk is full. Scanning in higher resolution results tons of Megabytes up to Gigabytes of scanning data that must be stored on your disk, cf. https://bugzilla.opensuse.org/show_bug.cgi?id=856794#c26
Hello. You don't view carrefully the attached files. They have nothing to do with iscan. They are relative to yast2. Concerning the disk full warning there is 60Gb free so I think it is sufficient. scanimage return this alert : "# scanimage -vvv -T scanimage: scanning image of size 1696x3743 pixels at 24 bits/pixel scanimage: acquiring RGB frame, 8 bits/sample scanimage: reading one scanline, 5088 bytes...

I am trying your recommendation by using traditional x86 32-bit software, and will give news asap.
While trying x86 driver, I have to keep x86_64 version of kipi-plugins-acquireimage and libksane0 because changing to 32 bits need to change many other things. I installed the 32 bits scanner driver. I still have a warning that the driver may failed on 64 bits system. It does not work. # lsusb Bus 002 Device 004: ID 04b8:0130 Seiko Epson Corp.

Same scanner, Same drivers and it's work on 13.1
