This one no longer applies to my tree due to some recent changes to the
option driver. Would you mind respinning it?

Please also place this one under the ALINK section and mention that
that's the VID that is used.

And perhaps you should put this one after the other ALINK entries
(including PID 0x9000) instead of with the DLINK ones.
