Does it work when you use it with scanimage multiple times?
Yes, Never any problem to use a xsane or gnome document scanner to scan. But I have built and installed airsaned on another ubuntu computer now, and it works without any issues. The only obvious difference is that the first one is connected with WiFi and the last (working) is connected with cable.
okt 16 16:34:19 spencer airsaned[6336]: sane_open(brother4:net1;dev0) -> SANE_Status Invalid argument
From your protocol, one can see that sane_open()
is unable to connect to the scanner, as if it has maybe changed its address?
AirSane is unloading SANE each time it gets a scanner's capabilities, or actually scans, so there cannot be a "memory" involved that would explain that it fails the second time each.
Indeed. There seems to be some issue with network configuration, configuring sane to use the IP address of the scanner instead of the hostname solves the issue. Thanks for the support.
Thanks for developing this program. I have an issue. Everything works fine first time after starting airsaned, any attempt after fails with

I'm happy to help with debugging if needed.
