I'm having the same problem with HP PSC 2175 scanner. Scanner ownership and permissions are defined in /etc/udev/permissions.d/50-udev.permissions. Ownership should belong to console user. A work around, since I don't know how to fix ownership, is to set permissions for usb/scanner* to 0666. What about when you switch off, and then on, the scanner? No switch on scanner, but disconnecting and reconnecting either power or usb cable make the scanner accessable to a non-root user. My earlier observation about permissions was probably a misinterpretation of steps that I took to get the scanner working. On one of many tests the scanner was accessable without having to disconnect and reconnect it. |
