Yes, the length seems to be different, using 46 as expected length
doesn't work for me:
[epson2] esci_request_identity2
[epson2] e2_cmd_info_block, params len = 2, reply len = 46, buf = 0xbf96b248
[epson2] e2_send: size = 2, reply = 50
[epson2] e2_send: ESC i
[epson2] buf[0] 1b .
[epson2] buf[1] 69 i
[epson2] e2_recv: size = 4, buf = 0xbf96afd2
Then, it locks up.
If I want to use the scanner, I have to restart it (the connexion didn't
end properly).
If I disable the identity2 request, I can use the scanner.
But an identity2 answer provides informations like the different
settings supported by the scanner, no? I think this is why xsane can't
get a preview (If I want to scan with xsane, I have to change the DPI,
otherwise, it fails).
