[sane-devel] Kyocera Scanner not working in any Linux Distro

[jitesh pandey]

Ok, thanks for reply, now take a look at the following, maybe you could
find something into it


*scanimage --list-devicesdevice `kyocera_gdi_a3:libusb:001:029' is a
Kyocera TASKalfa 1800 multi-functional device*

So scanimage list the device as *kyocera_gdi_a3 *but when I test it as

scanimage -d kyocera_gdi_a3 -T

*Output format is not set, using pnm as a default.scanimage: open of device
kyocera_gdi_a3 failed: Invalid argument*

So there is no luck in it further without any argument

SANE_DEBUG_KYOCERA_GDI_A3=255 scanimage -T
Output format is not set, using pnm as a default.
[kyocera_debug] Setting debug level of kyocera_gdi_a3 to 255.

I think there is problem in naming the scanner as it's not working
with *scanimage
-d [devicename]*
where devicename I have tried are kyocera, Kyocera_gdi_a3, Kyocera Taskalfa
1800, libusb:001:029 etc.
