Re: [Hp3300backend-devel] merging hp3300 package

[Bertrik S. <be...@zo...>]

As far as I can see, the libusb code is properly linked now.

I think it may help to comment out line 262 in hp3300c.c
(so the function does not return, but goes on) or
modify the ScannerModels list so that your scanner is recognised
as a hp3300c.
By the way, the testtool cannot actually do a scan with your
scanner, but you may be able to get basic communication working
and get some ideas about how to build the USB transfer layer.
I don't think that it's a good idea to try to merge hp2400 and
hp3300 code now (perhaps only the USB transfer code at some later
time when all similarities/differences have been figured out.

Regards,
Bertrik
