I've modified James Courtier-Dutton description from Optio 430 => Optio
2/3/400 since it applies to Optio 330 and possible 230 too.

Attached are the patch that was tried with Pentax Optio S and Optio 330 RS.
I've talked to Pete Zaitcev and he said I should be using CB instead since
more devices liked that better... so I leave that to you!
