Great!

"Should" is o.k. but please do not strictly forbid
to have more than one ":usbid" for one ":model"
and/or
to have the same ":usbid" for more than one ":model".


An example for both cases are the different model names
what the user can read on the scanner and what the scanner
reports via USB:


If the model name which the scanner reports via USB is
different but unique, there can be two entries like:

:model "Fun Scanner 1000" ; what is on the scanner
:usbid "0x1234" "0x4321"

:model "FS 1000" ; what the scanner reports via USB 
:usbid "0x1234" "0x4321"


If the model name which the scanner reports via USB is only
a generic name, the following should be posible:

:model "Fun Scanner 1000" ; what is on the scanner
:usbid "0x1234" "0x4321"

:model "Fun Scanner 1100" ; what is on the scanner
:usbid "0x1234" "0x4322"

:model "FS 1000 series" ; what the scanners report via USB
:usbid "0x1234" "0x4321"
:usbid "0x1234" "0x4322"


Another example for the second case are the different model names
in different countries - e.g. the Epson model names in Japan and
in the rest of the world.
