[sane-devel] coolscan2 in 1.0.8

[Major A]

Henning,

thanks for checking the code.

Done.

>     sanei_usb_attach_matching_devices ("usb Nikon *", cs2_attach);
>     sanei_usb_attach_matching_devices ("usb 0x04b0 *", cs2_attach);
>   
>   This won't work. The sanei function isn't that intelligent yet. You

I have no way of testing this, but from the feedback I got from an
LS-40 user I thought that this worked (not the first version, but the
second). As there is only one USB scanner in question, I've added the
explicit PID now.

Will check this later today.

OK, thanks.

OK, I'll do that just before the code makes it into SANE CVS. The only
two major deviations are long lines and "{", which I usually put in
the same line as the if/switch/etc.

> * There are some compilation warnings. At least those look more serious:

These come from the "z" type modifier in the output format string. Is
there any clean way of printing a size_t without using this modifier,
which is not supported in ISO C89?

Thanks,
