[sane-devel] Nikon LS50/5000

Hi Henning and thank you for your reply.

scanimage -L
device `epson:libusb:001:002' is a Epson GT-9300 flatbed scanner
device `coolscan2:usb:libusb:001:005' is a Nikon    LS-5000 ED       film 
scanner
So, the command would be scanimage -d coolscan2:usb:libusb:001:005 > photo
Which reproduced the same exact error, which is:
scanimage: sane_start: Error during device I/O

So, we are back to square one. Any idea on this?

Obviously not. I did only purchase this device, independently from which 
application to run. Thou, I did my research prior to purchasing it and came 
to the conclusion that VewScan is the only application (as of now) that is 
capable of running this specific device. I was/am counting on SANE because I 
like the idea to use it and am only thankfull to Ariel and whoever worked 
with Ariel for spending time for development.

Most likely it is a software feature which needs development too. So far, 
after I will solve my device I/O failure, what does SANE offer for this 
specific device? I do not mind waiting thou my photo project must start 
elsewhere.

I also offer my time and hardware for allowing some testing for as much as I 
am capable of. Obviously if Ariel or whoever is in need of and/or decides to.

So, please someone if possible advice me on how to solve this I/O issue.

thank you for now,
Spiro
