What you mean is you are confused at the set or get data by ways of the Report_ID via USB. Java and Linux have nothing to do with it. > Below are the ideas i tried in java.

Yes. > 2. I have no idea that which parameter should i set the > "Report_ID" (bmRequestType, bRequest, wValue, wIndex) It is very clear about this in the HID spec. Have you read the HID spec?

And you don't seem to have read the javadoc for the syncSubmit() and waitUntilComplete() methods. Read that javadoc so you understand what the contract for each method is. > > ------------------------------------------------------------------------------ > The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
