dff does:

: xdff
    " vendor-id" get-my-property IF ABORT THEN
    decode-int -rot 2drop   dup TO x93b   10de <> IF ABORT THEN
    " device-id" get-my-property IF ABORT THEN
...

so it seems the device-id or vendor-id propertie don't exist, or don't
have the right value?  Or you don't have a current instance, perhaps.
