Plugable USB to RS-232 DB9 Serial Adapter (Prolific PL2303HX) Not working on El Capitan. On most recent drivers. Anyone have a fix for this?

Hi Andrew,

Thank you for posting about this. El Capitan has added a new System Integrity Protection function that causes it to reject the current driver. We have a beta version of it that works, and I would be grateful if you would try it and give us your feedback.

I don’t want to post the link until it’s ready for release, but if you contact us at support@plugable.com, I will send you the link to it.

Thanks!

David
