As with most scanner manufacturers these days Microtek pays as little for<br>
|
|||
|
|
tech support people as possible. Most Linux (Unix) users are technologically<br>
|
|||
|
|
adept and therefore out of the price range of what Microtek's Tech Support<br>
|
|||
|
|
is willing to pay so therefore there are no current employees at Microtek<br>
|
|||
|
|
(that I'm aware of) that are (Linux) Unix users. The programmers there are<br>
|
|||
|
|
interested in Mac and PC only because that's what pays the bills. I<br>
|
|||
|
|
personally know some people within the company so sometimes I can get them<br>
|
|||
|
|
to cough up some documentation. I've forwarded this conversation thread to<br>
|
|||
|
|
them so maybe they can be shamed into providing what's needed. ;-)<br>
