Support for Avision PaperAir 215 Document scanner?
Hi, I did some investigations on the currently unsupported document scanner. Weather Avision declares Linux compatibility, neither SANE lists it as supported by the Avision backend. It is currently also not supported by the company binary SANE driver package #498 (closed).
Of course it is detected on the OS level:
dmesg ... [18429.205060] usb 2-1.2: new high-speed USB device number 4 using ehci-pci [18431.230635] usb 2-1.2: New USB device found, idVendor=0638, idProduct=2d02, bcdDevice= 1.15 [18431.230654] usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [18431.230661] usb 2-1.2: Product: PaperAir 215 [18431.230665] usb 2-1.2: Manufacturer: AVISION [18431.230670] usb 2-1.2: SerialNumber: A09081987A330187
This makes it possible to guess it for SANE as well:
sudo 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.

But of course it fails to use it properly. If we make a detailed guess:
sudo sane-find-scanner -v -v This is sane-find-scanner from sane-backends 1.1.1-debian

I read that the backend is currently unmaintained, so I'm not sure what to do ...
P.S: I asked support@avision-europe.com and service@avision-europe.com if they would share some technical documentation to enable at least unofficial SANE support, but unfortunately no feedback for now.
