[sane-devel] Get the devices about sane

[m. allan noah]

Are you saying that the backend does not work when you remove the
debugging? This sounds like you have a timing problem, and the
debugging info slows down the backend, so that the scanner can keep
up. You might need to add some sleep() or usleep() to the code.
