Both the USB bus and the SCSI bus can give you an aweful lot of information. You can enable debugging options to the extent that every byte passing the bus is detected. It does help, though, if the scanner is the only device with that bus on the computer because otherwise you might have to filter the scanner's data out of a huge stream of messages. The only time this is not a problem is when you only obtain log messages from the USB scanner module, because those logs will only come from the communication with the scanner. > I didn't understand all what you say because I don't know what does even > mean "sane2 standard" (sorry), but I'll read some documentation about > this, and I'll soon be able to give you a correct answer ;-) The SANE standard describes the interface between frontend and backend. Currently it isn't flexible enough to support such things as colour management, therefore such extensions should be added at some stage to make film scanning (and high-fidelity colour scanning in general) much easier. For the time being, don't worry about the frontend, the protocol is everything, actually coding a backend when you have it is relatively simple. > Thank you very much for all this software I didn't even know before. > I've downloaded them all.

You can also log directly under Linux -- provided VueScan works (preferably with both interfaces). VueScan uses the sg and scanner modules to access SCSI and USB scanners, and kernel logging can be used to dump the data.
