Hello Steven,

May be I can answer the first and the second question.

As you can see in the following url, HP 3970 scanner is not supported at all.

There isn't any code for this scanner's chip (RTS8822-01) and as I can
see, it's functionability is a bit different from Realtek RTS8801B chip,
used in other scanners:

Unofficially, I've started to study this scanner two months ago, debugging
instruction by instruction the library that manages the scanner in windows
system (hpgt3970.dll). It's a very slow proccess. I don't know how much
time will I spend before releasing a functional demo program.

Main functions in that library are:
HP_OP_INIT_SCANNER : Debugged and implemented succesfully.
RT_OP_SET_PARAMETER: Debugged an implemented succesfully.
RT_OP_START_SCAN   : Already debugging.
RT_OP_READ_IMAGE   : Not debugged

Sincerelly, JKD

P.D.: I apologize about my english level
