I have a printer 'Epson Stylus Sx115' plugged into my USB port.
It is detected because it is listed in lsusb

I have CUPS installed as well as Gutenprint and the Epson driver from Avasys.
However, when adding a new printer CUPS does not detect it so I can't install it.
CUPS seems to be working because it is detecting my network printer (Brother DCP).
How can I install my Epson printer?
PS: I tried disabling the usblp module but without result.


/usr/lib/cups/backend/usb, too? (That's what CUPS sees.) – sr_ Mar 19 '12 at 16:11dmesgsay when you plug it in? – Kevin Mar 21 '12 at 17:48
