I got it working, although I am not really sure that it does not contain faults in some corner cases. As we are pretty close to the 1.0.23 release of sane, I will not yet commit the changes to git. It took me quite a while to figure out how the protocol works, so it has taken quite some time before I got something working.
Please let me know if you are in a hurry to test before the 1.0.23 release is done. If so, I can mail you a patch to apply on top of the current git. I have only tested this with xsane, as I did not have time to setup scanbd, sorry. It anyhow looks as if sane and printing (bjnp backend for cups) can access the device at the same time: I could print a page while xsane was waiting for a button to be pressed. When the printjob was done, I was able to press the scan button again. Louis P.s. I will push my changes to git as soon as 1.0.23 is released
