Hi Henning and thank you for your reply. 1) > man scanimage > scanimage --help > scanimage -d coolscan2 > photo.pnm
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? 2) > > > Well, this is not sufficent for allowing a user to fully utilize what was > > purchased (in my openion). I purchased this device becaue of all its > > features.

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. 3) > > > For sure you know this scanner better than I do just because you are > > deveoloping the driver, but I wish to ask you a question then: How come > > VieScan allows all customizations? > > Perhaps the Vuescan author just implemented all the features in > software? You are free to do so in SANE also, i.e. it's not impossible > or forbidden, it just hasn't been done yet in this case. 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
