Gerhard, I assume the typo in Plustek-USB.txt got fixed.
I also assume that someone is looking for the "off" switch for the light. To clarify further what I said about this, let me add that, by visual inspection, the head appears to return correctly to its "park" position after a scan, but the light remains lit.

One of the biggest parts of doing the job right is figuring out creative ways to get people to pay attention and actually to assimilate what you are telling them. And, naturally, even if we told them and they didn't understand it is still our fault. Goes with the territory. You really have to put up big signs, and still some will read without understanding. > > > 5. I didn't try the buttons.

I can't quite see why the buttons were put on in the first place, taking into consideration what they are supposed to do. Their functions seemed to me to be very Windows-specific. Things like "scan this and attach it to the e-mail I am composing right now." Seems silly to us Linux people, doesn't it? However, we should remember that there are other people out there who like such features in Windows, or at least are used to them. Come to think of it, I do have a suggestion about such matters: If the effect of the button pushes could somehow be trapped by some program similar to "dumpkeys," and (for example) then mapped to start a specific command by some file like keytable.map then it would be quite easy to write script frontends which would be triggered when such a "signal" is received and then start up the right program (for example, xsane), and then do with the output what the user would reasonably expect... As an analogy, I just love to run mc, and on several machines I fixed it so that F12 is mapped to a command to start Midnight commander, until I finally overcame my laziness about typing mc and hitting <ENTER>. The first thing would be to have available a daemon which would trap those specific signals coming in over the USB port, WITHOUT having already started a SANE program, because the idea would be then to start SANE to do some specific task. Gerhard, this is not a job for either of us, I suspect. Certainly I am not trying to get you to drop everything and work on it. But perhaps somebody else will read this and think about it.
