Re: [sane-devel] Possible Sponsorship for Avision Backend Modification

[daniel]

Hi René,

Thanks for contacting me.

Would that mean an entirely new backend would be required?

Right now I am developing my own driver with libUsb in my own app. Its prrtty painful but I am making slow slow progress. It might even be work.

If that fails I'll ask for help with SANE. How much has such activities cost in the past?

Thanks,

Daniel Wilson

Hey Daniel,

while I’m certainly open for contracted modifications to the avision backend I wrote, your device is most likely not using the classic Avision protocol

Best regards,

Hi all,

I tried to download the source, and get editing. I am a competent programmer (was my fun time job for 3 years) but I've never worked with C or C++.

Got lost at trying to build an environment that supported debugging. Some error about a missing file when I attempted to compile.

My use case for the scanner is very simple. I just need a simple colour scan at a set dpi. Don't need any fancy features. (not sure if that helps or not)

Is anyone here capable of adding a device to the Avision driver? I can supply a ssh into a device connected to the scanner.

Any idea of how much this would cost?

Below is the initial call for help I sent out last week regarding the device

Thanks!

Hello all,

Been trying to get a scanner with an avision scanner to work. The scanner name is "WorldCard Pro (Win/Mac)" http://www.penpowerinc.com/product.asp?sn=407

It's not listed as supported, but thought I might get lucky. My thinking was that if it's supported by Mac, it should work with linux. Tried specifying all sorts of values in /etc/sane.d/avision.conf but nothing seemed to work.

Is there a way to add support to the existing avision backend?

Thanks for  your help!

Daniel
