     Hello,

     I have reviewed latest changes, and I consider that the pieusb 
backend is ready for inclusion since commit 
e6294630553b5bcb2671537786c5107e3393ac9f on the pieusb branch of 
git at github.com:kkaempf/sane-backends.git .

     I suppose you'll create an account on alioth 
(https://alioth.debian.org/account/register.php) so that Allan can add 
you to the project.

     I would be really great if you could extract the buffer bits in a 
sanei_buffer, it would be an added bonus for the project. But it is a 
separate issue from backend inclusion.

     Many thanks for this nice work.

     Allan, adding a backend requires you re-run config script on 
alioth, isn't-it ?

Regards,
     Stef
