El Capitan Keyspan Adapter Support
I started doing some research after reading this post about having to manually enable support for USB to Serial keyspan adapters. Believe it or not I use the Tripp Lite USA-19HS on at least a weekly basis and is an upgrade deal breaker if support has been eliminated or if the manual steps to enabling support are unwise. Anyone have thoughts on this?
Thanks in advance.

Mike416, thought I'd check in with a bit of good news.
After doing a bit more research it seemed like every upgrade to the MacOS was sketchy concerning keyspan adapters. So I took the plunge. There was no way to test whether my keyspan was working until I arrived at my job site today. Sadly, the El Cap upgrade broke the driver and the fresh install of the USA-49WG didn't even run. It failed immediately.
What was strange was that in the System Profiler the USB section displayed the device perfectly, even listing my model USA-19HS.
So I took the following steps, staying completely away from the Keyspan Serial Assistant. I went to System Prefs, Network, and removed any devices (I think they showed up as modems) and rebooted to have the changes take effect. Then I downloaded a driver for 10.10 found on this Tripplite page (though I don't know if it will work), it's a driver written for 10.9 and 10.10. Downloaded that, ran the installer, and voila, worked like nothing had ever happened.
