Comment 6 for bug 468701

I have a very similar problem. I had Ubuntu 9.04 and hplip 3.9.8 and both a parallel all-in-one and a usb all-in-one installed. Both AIO's worked under HP Director for printing and scanning. I upgraded to Ubuntu 9.10 and the usb AIO is no longer recognized by HP Director. Using System>Administration>Printing I can install both printers. Both AIO's work fine under XP. I installed 3.9.10 after uninstalling 3.9.8, same result, no usb under HP Director. As a test, I installed 3.9.8 on a different computer running Ubuntu 9.04. Both AOI"s again worked normally for printing and scanning. Under 9.10, running hp-check says "no usb devices found" and says that " sudo aptitude install --assume-yes cupsddk cupsddk-drivers" should be run to remove the errors (this does nothing, hp-check will return the same errors). My analysis is that there is a disconnect between cups 1.4.1 and Ubuntu 9.10 There is also a disconnect between hp-check and cups 1.4.1. I hope this helps to pinpoint and correct the problems.
