Thanx to all those who responded to my device driver query. Although
I received many reply's asking for the results, I got relatively few
suggestions on where to look for a good "how-to" manual. Here are the
replies, edited to protect the names of the innocent:

Hope this'll help some more of you folks. To those who mailed, requesting
this information, here it is.
