<EM>> Hello,
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Glenn Ramsey and me wrote a scanning application for the Microtek 3600
|
|
</EM><BR>
|
|
<EM>> USB scanner. It is pure reverse engineering, since we got no information
|
|
</EM><BR>
|
|
<EM>> at all from Microtek until now. Thus the driver uses very much magic
|
|
</EM><BR>
|
|
<EM>> control values. But it works for at least Glenn and me. And if You test
|
|
</EM><BR>
|
|
<EM>> it with us, we can make it just better.
|
|
</EM><BR>
|
|
<P>Great work !
|
|
<BR>
|
|
<P>[..]
|
|
<BR>
|
|
<EM>> So we will apprechiate any information pointer for SANE integrations
|
|
</EM><BR>
|
|
<EM>> aspects, especially how to
|
|
</EM><BR>
|
|
<EM>> - link the backend as a SANE DLL module
|
|
</EM><BR>
|
|
<EM>> - install the additional backend by hand
|
|
</EM><BR>
|
|
<EM>> - address the usbfs root access issues in a sensible manner.
|
|
</EM><BR>
|
|
<P>This is a general problem.
|
|
<BR>
|
|
You can either live with it and use saned over TCP/IP loopback, which I
|
|
<BR>
|
|
wouldn't recommend.
|
|
<BR>
|
|
Or you change the permissions and ownership on the usbdevfs entry.
|
|
<BR>
|
|
Or write a small kernel module.
|
|
<BR>
|
|
If you have libusb available under a range of platforms this is more portable.
|
|
<BR>
|
|
However the permissions solution works on Linux and only with usb hotplugging
|
|
<BR>
|
|
support (or manually which is too ugly to let live).
|
|
<BR>
|
|
You clearly cannot use the existing kernel drivers.
|
|
<BR>
|
|
As for portability, I only know that BSD has generic USB drivers as regular
|
|
<BR>
|
|
devices which will use the same permission system as all other device files.
|
|
<BR>
|
|
Is there any other Unix with USB support ?
|
|
<BR>
