That would have been me.<br>

I very much doubt that they are correct.<br>

You choose wrong.<br>

UMAX have repeatedly refused to give me the necessary programming<br>
|
||
|
|
information for the parallel port protocol The reason given to me was<br>
|
||
|
|
that the only documentation on the parallel port protocol is combined<br>
|
||
|
|
with the documentation on the design of the ASIC. Umax are under the<br>
|
||
|
|
delusional belief that their ASIC is something special and the design<br>
|
||
|
|
needs to be protected. Why anyone would want to copy a design that only<br>
|
||
|
|
uses only SPP and EPP modes (that's right no PS/2 or ECP) is beyond me.<br>
|
||
|
|
There was also some suggestion that the ASIC design may have been licesened<br>
|
||
|
|
to other scanner manufacturers (more fool them).<br>
|
||
|
|
<p>
|
||
|
|
The scanner can be used in a limited extent under Wine, and should not be<br>
|
||
|
|
too hard to reverse engineer. There are only seven routines in the driver<br>
|
||
|
|
that do any sort of communication with the scanner and I had little trouble<br>
|
||
|
|
working out the SPP ones (there are 14 in reality 7 SPP and 7 corresponding<br>
|
||
|
|
EPP ones). It is just a case of understanding these and putting them<br>
|
||
|
|
back together.<br>
|
||
|
|
<p>
|
||
|
|
I was this time last year working on reverse engineering this protocol,<br>
|
||
|
|
however this work has been indefinately suspended since the begining of<br>
|
||
|
|
February this year. The reason being that whilst working on reverse<br>
|
||
|
|
engineering the protocol I had a flash of inspiration that lead me to<br>
|
||
|
|
workout a much longer term reverse engineering project I have had, namely<br>
|
||
|
|
being able to set the battery saving options on Toshiba laptops (ie. a<br>
|
||
|
|
Linux port of MaxTime).<br>
|
||
|
|
<p>
|
||
|
|
This has progressed to the point now where there are three laptops in<br>
|
||
|
|
transit from Toshiba Germany to me as I type this, for testing purposes.<br>
|
||
|
|
When I have finished with these I can return them and get some more etc.<br>
|
||
|
|
This is likely to keep me busy indefinately, and because of this I am<br>
|
||
|
|
likely to flog my scanner on to a friend who uses Windows and get a<br>
|
||
|
|
different scanner that does work under Linux (anyone tried getting the<br>
|
||
|
|
docs for the HP 4100 USB scanner?).<br>
