http://www.usb.org/developers/defined_class/#BaseClass06h www.usb.org/developers/devclass_docs/usb_still_img10.pdf When we were developing our scanners, we looked into the USB still imaging device. The spec is huge and, IIRC, parts of it require paying for (PIMA15740? ISO15740? I can't remember). We decided to come up with our own because it was faster, easier, there was no real standard anyway, and we could test both ends in-house. With our own protocol, we could do our own testing and not worry about testing interoperability with 'N' different stacks. I'm not saying creating our own protocol was a perfect solution. It was the best solution we had at the time. But we did try to make it easy to reverse engineer. -----Original Message----- From: [email protected] on behalf of Paul Wise Sent: Sun 12/28/2008 4:04 PM To: sane-devel Subject: Re: [sane-devel] SANE protocol over USB as new USB scannerdevice class?
