I have an old HP Photosmart 7960 USB printer that has worked very
well over the years. Two days ago I noticed that, all of a sudden, it
stopped working. I started and stopped CUPS several times, to no avail. I
even rebooted the system (Slackware 14.2) again without success. What is
intriguing is that the printer cannot be seen even at USB level - the
outout from lsusb -v is the same, whether or not the printer is plugged
into the USB port. Any USB port, at that.
I can accept that a particular USB port has gone bad, but not all
of them. At any rate, when I plug in other devices (e.g. USB sticks,
phones) they clearly work. I am uttely puzzled as to why this printer,
all of a sudden, can't at all be seen by my Slackware 14.2 box. I have
not been installing any third party software; I have just been keeping up
to date with patches for Slackware 14.2.
