Yes, I think you are confused a lot ;-) > Q2 : Did you claim the interface?

Please give me any advise, direction, or correct if you have any doubts. I'm sorry, but I have repeatedly told you to read the HID spec and I don't believe that you have even downloaded it. You seem to just want me to tell you exactly what to do. So I will state ONE MORE TIME: you need to download and read the HID spec. Until you do, I am not going to answer any more of your questions. To make it really easy on you; here is the link to get the spec: http://www.usb.org/developers/devclass_docs/HID1_11.pdf Once you download and read the spec, reply with the specific section number that describes a "Get Report" request. Then I'll know you have at least downloaded and browsed it, and I'll be glad to clarify the spec for you. Again, sorry, but I won't do your work for you. > 4.

Your production scanning environment may not be a perfect world - but thanks to Kodak, there's a perfect scanner to get the job done! With the NEW KODAK i700 Series Scanner you'll get full speed at 300 dpi even with all image processing features enabled. http://p.sf.net/sfu/kodak-com _______________________________________________ javax-usb-devel mailing list javax-usb-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/javax-usb-devel
