Ok, sorry, this is awkward. I plugged-in the USP-1284 again, and now it works just the same as the RCW-602, also reporting the Device ID. This is with cups version 1.5.0-13, released 2011-12-02, and with kernel 3.1.0-1-686-pae.
So, cups seems to be working now, for me, and I may have had a connector problem or some such for a while with that one adapter. James -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
