That=20 is one of the programs that intercept data between the host and the=20 device. It is in the sane CVS, co experimental.=20 Two scans of the same image would be more helpful. What I am looking for is to identify the vendor commands that set register values. =20 I have not been able to identify a vendor write or vendor read command ye= t. A greyscale 8-bit depth and a color at 16 bits would be excellent. Any image should do to get further progress on this backend. The smallest scan image would be best, as only 1 square centimeter is=20 needed for what I am seeking.
The gl841 chip has two bulk endpoints, and I will be looking for log=20 information that would tell me whether any commands were sent down the bulk out pipe. I will try to get the snoopy program working here so that I can find out how to use that tool. =20 Thanks for your encouraging response. Gerald > regards >=20 > werner --=20
