Hi,

I'm struggling with a 3170 Epson scanner, trying to make it work under 
NetBSD-current.

As far as I have understood, the communication protocol used over USB is 
not Twain based, therefore non-standard and not-supported by Sane and 
its derivatives.

However, there seems to be a program working under Linux called "iscan", 
which handles this particular scanner. Unfortunately, since the protocol 
is not open, the object files which implement it are given out only as 
.o objets, unlinkable under NetBSD (as far as I know).

So, I fetched the binary distribution. But, even when all proper Linux 
librairies are installed, it seems not to work; thus I would like to 
ask, before continuing tinkering, if:

1. the USB emulation layer (Linux <> NetBSD) works, so if we can expect 
a 'normal' behaviour from the Linux version of libusb.so ? (That's for 
tech-kern)

2. If I compile the libusb package with a Linux GCC using the BSD 
headers, will I produce a 'usable' libusb, that is, loadable under Linux 
and producing direct NetBSD USB calls ? (That for tech-kern/current-users !)

3. Or does anybody know about iscan for NetBSD ?

4. Has anybody done anything like this ?

Thanks, cheers !
