And MP210 should not be declared here, so this is maybe an issue due to
Slackware, as Sane packages do not ship with that.

The usb pids are hold directly in the pixma backend, this is because the
Canon Pixma protocol exists in fact in about 10 different flavours, the
pixma backend supports currently 67 different Pixma/I-Sensys/ImageClass
models, and different code is used according to the model group. Each
time a new model is added, a check must be done to see which Pixma
protocol is involved. So adding a new model requires a recompilation of
the backend.
