@Lorenzo : Yes and several times because as I sell Ubuntu computers, I have several clients with Lexmark printers that just cannot use it.
it's not always possible to downgrade ubuntu, like Intel Ivy bridge support.
I tried to downgrade CUPS to 1.4.X from Natty but it would just downgrade the whole Ubuntu desktop.
BTW : I successfully installed a x4650 (Same probleme as s405) on Ubuntu 12.04 over Wifi. I had to install the cups filter but it now works great.
So as I understood before , the issue seems to be only related to Usb/cups.
@Till : could you update the description and detail the USB stuff ? because your explanations are lost in comments.
