Re: [Hp5400backend-devel] hp5400c/freebsd-4.8/

[Thomas S. <sou...@ne...>]

I only see at this moment 3 options :
* it might be a problem with big and little endian. Commands sent to the=20
scanner are array of chars and could be affected by the byte order your=20
system use. If it is that it would explain that the scanner does receive wh=
at=20
we think we do and therefore does not reply as we expect
* it could be a problem with permissioning ?
* the scanner has not the same chipset. To check that you would have to get=
 a=20
USB log from its communication under a supported OS (e.g. Windows). Your=20
could log just the startup of a scanning program, then send it to me so I=20
could tell you if it talks the same way.

Do you have knowledge about C programming ?
