Not being able to find a scanner doesn't mean sane isn't installed

thanks for the info, I have used it and sane is installed, but alas the scanner still remains unreachable, I previously used an epson px660 which worked fine but I have had to replace my printer, I now have an epson xp645, the printer functions perfectly but not the scanner, any ideas.

Have you installed the scanner driver that you can download from http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX&productName=XP-645 ?

Hi, Yes I have just done that again as that is were I got the drivers
for the previous printer and scanner from, I have also repositioned the
usb lead into a port directly fitted to the board as opposed to a port
at the top of the casing, which I thought might be just a remote hub and
not recognised by the software, I am still getting the same message
about scanner not present and when I use the scanner buttons I get the
message check if computer is connected.

For diagnostic purposes:

1. Check whether the scanner is identified at all:
Unplug the USB-cable of the scanner
issue the command "dmesg"
note the time code of the last line of the output.
plug the USB cable of the scanner into the computer
wait 30 seconds
re-issue the command "dmesg"
Are there any new lines now (with a time code higher than before)?
What is the output of the command "lsusb"?

2. Can you try the scanning program that comes with the Epson software by execting the command "imagescan"?

Hi Manfred,

tried your idea of unplugging the cable and using the dmesg command, low
and behold the scanner is listed as an epson device, now if I use the
scan program it works just fine as long as I use it from the computer
program and not the scan button on the printer, which I can live with,

Thanks very much for your expertise,

regards Alan Longman
