[cups.development] CUPS not detect the USB printer connected

[Michael Sweet]

Sounds like a permissions problem - the USB backend runs as the "lp" user by default, so the USB device files will need to be writable by "lp" or have the appropriate group with group write enabled.

I could see the device connected in /proc/bus/usb/devices & /usr/share/cups/backend/usb also shows the printer connected. But my lpinfo -v command shows always 5 other devices (http, ipp, socket, lpd & scsi).
