I modprobe'd usblp module and my printer is again working. Thanks Rusi

Yes I gathered (something like) this is the issue, though I dont understand the details. Is it possible to reverse the blacklisting and see what happens?

What versions of udev and the kernel do you use? Does /etc/udev/rules.d contain any custom entries? Not sure how this is best checked. Synaptic shows udev and libudev0 as installed: 171-3 latest: 172-1 That is it is upgradable. I can try doing that but dont know if this will only muddy the waters further :-) As for kernel: uname gives me 2.6.32-5-686 synaptic for linux-image-2.6.32.5-686 shows installed version at 2.6.32-31 same as latest Small addition. Just noticed this: The devices were originally appearing and disappearing on switching printer on and off under /dev/usb on the old working system On the new system I see similar behavior under /dev/bus/usb I guess I will just have to run the ccpdadmin command with the changed path. [Ive forgotten the command -- will have to fish it out] Does this seem appropriate?
