Hmm, I'm not entirely convinced there is a bug here... I don't have your |
| 32 |
particular situation, but on my system, cupsd runs as root, which means that |
| 33 |
it should be able to access the device just fine, whether it's set up as lp |
| 34 |
or usb. Is it possible that the user that you are logged in as isn't a |
| 35 |
member of the "usb" group? |
