I have the same problem with an Epson CX-4600. It has a memory card reader in addition to printer and scanner, so the workaround requires blacklisting or removing both usblp and usb-storage modules. As a result, usblp must be removed to scan and re-loaded to print. Furthermore, scanning isn't possible when usb storage (e.g. an external drive) is mounted, since the usb-storage module can't then be unloaded.
The problem didn't exist in wheezy. Is a "real" fix in the works, perhaps upstream? Thanks.. Bill -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
