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

[jitesh pandey]

Dear Ralph, I tried your suggestion, as the output I got was not that big
so I am pasting here for better explanation, as you can see we are getting
the same invalid argument error.

*LIBUSB_DEBUG=10 scanimage -d kyocera_gdi_a3 -T*
Output format is not set, using pnm as a default.
