Hi, and thanks. I don't know what this error means. Could this have
something to do with permissions. I don't know the USB protocol well
enough to tell if there is anything odd in the configuration or not.

My 8800F gives the following (as root) using the same setup and command:

1) the result of the pixma backend during the scanning using all backend:

2) the opening of the device after scanning of backends is complete
and the 8800F is selected for operation:
