Huh? Initialising the device fails? Weird. Looking over the debugging output in your previous mail _all_ commands sent to the device fail and return a NAK (hexadecimal code 15). That doesn't look right. It can't be a permission problem because then you would not even be allowed to send commands (let alone get a reply ;-) I wondering whether the transfer of the firmware file went allright and whether you have the right file. First, check the firmware file like so: $ md5sum <path_to_iscan_data>/esfw43.bin 0ea6ea67218298305e991436ed73c07e <path_to_iscan_data>/esfw43.bin The MD5 checksum you get should be the same as above. <path_to_iscan_data> is probably /usr/share/iscan/, you can check with `dpkg -L iscan-plugin-gt-f600` to make sure. If that's okay, power cycle the device and run the following command (make sure you have sufficient permissions to access the device): $ SANE_DEBUG_SANEI_USB=127 SANE_DEBUG_EPKOWA=127 scanimage --help &> debug.log and send the debug.log file (as an attachment, please) to me (or the list). > [epkowa] close_scanner(fd = 0) > scanimage: sane_start: Invalid argument > [epkowa] close_scanner(fd = -1) > scanimage: WARNING: read more data than announced by backend (0/3000582144) > [epkowa] close_scanner(fd = -1) > [epkowa] sane_exit > > [snip] -- Olaf Meeuwissen EPSON AVASYS Corporation, SE1 FSF Associate Member #1962 sign up at http://member.fsf.org/ GnuPG key: 6BE37D90/AB6B 0D1F 99E7 1BF5 EB97 976A 16C7 F27D 6BE3 7D90 Penguin's lib! -- I hack, therefore I am -- LPIC-2
