interop with alexpevzner/sane-airscan fails #76

Open markosjal opened 2 years ago

markosjal commented 2 years ago

Just FYI , testing interoperability with alexpevzner/sane-airscan Multi Page scanning from ADF fails.

Please see attached wireshark pcap . Sorry because it is a 'localhost' connection it can be hard to follow (same IP to/from Same IP)

At packet number 1031 you see "409 Unknown Reason" . I believe that is the point where it all falls apart in Document scanner 3.36.3

This was tested on a new install of Linux Mint 20.2 Uma base: Ubuntu 20.04 focal. AirSane Was installed right after your addition of "Serial Number" in xml.

The capture file is here http://portlandtel.com/pcap/eSCLFailpcapng.zip

Bug report for alexpevzner/sane-airscan is here https://github.com/alexpevzner/sane-airscan/issues/171

409 means "Hardware Conflict" and, in this case, indicates that SANE reports an empty ADF.

But not empty. There were 4 pages loaded in adf . First scans successfully and does second page which displays.second , then seems to disappear from Scan app at about the time of this error. In other words This second page appears then after the display of the second page disappears although scanner is very fast and all scanning from ADF may have actually completed .

ADF support is broken in AirSane. @ShadesJeff has created a fork that is supposed to fix it: https://github.com/ShadesJeff/AirSane. Maybe you give that a try?

markosjal commented 10 months ago

Is ADF still broken?

SimulPiscator commented 3 months ago

ADF code has been reworked in commit 26d70d4
