When I run lpinfo -v, there are a number of entries for usb which are:

direct usb:/dev/usb/lp0
...up to...
direct usb:/dev/usb/lp15

But no entry referring to my printer in the usb://DSC?=serial form.

I looked in the cups compile options, and could see no option to specifically switch the feature on or off. Can you think of why there are only the /dev/usb/ entries?
